- Update to 0.103.6
* CVE-2022-20770: Fixed a possible infinite loop vulnerability in the CHM
file parser. Issue affects versions 0.104.0 through 0.104.2 and LTS
version 0.103.5 and prior versions.
* CVE-2022-20796: Fixed a possible NULL-pointer dereference crash in the
scan verdict cache check. Issue affects versions 0.103.4, 0.103.5,
0.104.1, and 0.104.2.
* CVE-2022-20771: Fixed a possible infinite loop vulnerability in the
TIFF file parser. Issue affects versions 0.104.0 through 0.104.2 and
LTS version 0.103.5 and prior versions. The issue only occurs if the
"--alert-broken-media" ClamScan option is enabled. For ClamD, the
affected option is "AlertBrokenMedia yes", and for libclamav it is the
"CL_SCAN_HEURISTIC_BROKEN_MEDIA" scan option.
* CVE-2022-20785: Fixed a possible memory leak in the HTML file parser /
Javascript normalizer. Issue affects versions 0.104.0 through 0.104.2
and LTS version 0.103.5 and prior versions.
* CVE-2022-20792: Fixed a possible multi-byte heap buffer overflow write
vulnerability in the signature database load module. The fix was to
update the vendored regex library to the latest version. Issue affects
versions 0.104.0 through 0.104.2 and LTS version 0.103.5 and prior
versions.
* ClamOnAcc: Fixed a number of assorted stability issues and added
niceties for debugging ClamOnAcc.
* Fixed an issue causing byte-compare subsignatures to cause an alert
when they match even if other conditions of the given logical
signatures were not met.
* Fix memleak when using multiple byte-compare subsignatures. This fix
was backported from 0.104.0.
* Assorted bug fixes and improvements.

- Update to 0.103.5
* CVE-2022-20698: Fix for invalid pointer read that may cause a crash.
This issue affects 0.104.1, 0.103.4 and prior when ClamAV is compiled
with libjson-c and the CL_SCAN_GENERAL_COLLECT_METADATA scan option
(the clamscan --gen-json option) is enabled.
* Fixed ability to disable the file size limit with libclamav C API,
like this:
cl_engine_set_num(engine, CL_ENGINE_MAX_FILESIZE, 0);
This issue didn't affect ClamD or ClamScan which also can disable the
limit by setting it to zero using MaxFileSize 0 in clamd.conf for ClamD,
or clamscan --max-filesize=0 for ClamScan.
Note: Internally, the max file size is still set to 2 GiB. Disabling the
limit for a scan will fall back on the internal 2 GiB limitation.
* Increased the maximum line length for ClamAV config files from 512 bytes
to 1,024 bytes to allow for longer config option strings.
* SigTool: Fix insufficient buffer size for --list-sigs that caused a
failure when listing a database containing one or more very long
signatures. This fix was backported from 0.104.

OBS-URL: https://build.opensuse.org/package/show/security/clamav?expand=0&rev=225
- Update to 0.103.4
* FreshClam:
- Add a 24-hour cool-down for FreshClam clients that have received
an HTTP 403 (Forbidden) response from the CDN. This is to reduce
the volume of 403-response data served to blocked FreshClam
clients that are configured with a tight update-loop.
- Fixed a bug where FreshClam treats an empty CDIFF as an
incremental update failure instead of as an intentional request
to download the whole CVD.
* ClamDScan: Fix a scan error when broken symlinks are encountered on
macOS with "FollowDirectorySymlinks" and "FollowFileSymlinks"
options disabled.
* Overhauled the scan recursion / nested archive extraction logic and
added new limits on embedded file-type recognition performed during
the "raw" scan of each file. This limits embedded file-type
misidentification and prevents detecting embedded file content that
is found/extracted and scanned at other layers in the scanning
process.
* Fix an issue with the FMap module that failed to read from some
nested files.
* Fixed an issue where failing to load some rules from a Yara file
containing multiple rules may cause a crash.
* Fixed assorted compiler warnings.
* Fixed assorted Coverity static code analysis issues.
* Scan limits:
- Added virus-name suffixes to the alerts that trigger when a scan
limit has been exceeded. Rather than simply
Heuristics.Limits.Exceeded, you may now see limit-specific
virus-names, to include:
+ Heuristics.Limits.Exceeded.MaxFileSize

* Fixed a scan performance issue when ENGINE_OPTIONS_FORCE_TO_DISK is
enabled. This issue did not impacted most users but for those
affected it caused every scanned file to be copied to the temp
directory before the scan.
* Fix ClamDScan crashes when using the --fdpass --multiscan
command-line options in combination with the ClamD ExcludePath
config file options.
* Fixed an issue where the mirrors.dat file is owned by root when
starting as root (or with sudo) and using daemon-mode. File
ownership will be set to the DatabaseOwner just before FreshClam
switches to run as that user.
* Renamed the mirrors.dat file to freshclam.dat.
* Disabled the HTTPUserAgent config option if the DatabaseMirror uses
clamav.net. This will prevent users from being inadvertently blocked
and will ensure that we can keep better metrics on which ClamAV
versions are being used.
* Moved the detection for Heuristics.PNG.CVE-2010-1205 behind the
ClamScan --alert-broken-media option (ClamD AlertBrokenMedia yes)
option. This type of PNG issue appears to be common enough to be an
annoyance, and the CVE is old enough that no one should be
vulnerable at this point.

* Fix ClamOnAcc scan on file-creation race condition so files are
scanned after their contents are written.
* FreshClam: Deprecate the SafeBrowsing config option. The
SafeBrowsing option will no longer do anything.
* For more details, see our blog post from last year about the
future of the ClamAV Safe Browsing database.
* FreshClam: Improved HTTP 304, 403, & 429 handling.
* FreshClam: Added back the mirrors.dat file to the database directory.
* FreshClam will now exit with a failure in daemon mode if an HTTP 403
(Forbidden) was received, because retrying later won't help any. The
FreshClam user will have to take actions to get unblocked.
* Fix the FreshClam mirror-sync issue where a downloaded database is
"older than the version advertised."

- Update to 0.103.1
* Added a new scan option to alert on broken media (graphics) file
formats. This feature mitigates the risk of malformed media files
intended to exploit vulnerabilities in other software. At present
media validation exists for JPEG, TIFF, PNG, and GIF files. To
enable this feature, set AlertBrokenMedia yes in clamd.conf, or
use the --alert-broken-media option when using clamscan. These
options are disabled by default in this patch release, but may be
enabled in a subsequent release. Application developers may enable
this scan option by enabling CL_SCAN_HEURISTIC_BROKEN_MEDIA for
the heuristic scan option bit field.
* Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing
behavior. BMP and JPEG 2000 files will continue to detect as
CL_TYPE_GRAPHICS because ClamAV does not yet have BMP or JPEG
2000 format checking capabilities.
* Fixed PNG parser logic bugs that caused an excess of parsing
errors and fixed a stack exhaustion issue affecting some systems
when scanning PNG files. PNG file type detection was disabled via
signature database update for ClamAV version 0.103.0 to mitigate
the effects from these bugs.
* Fixed an issue where PNG and GIF files no longer work with
Target:5 graphics signatures if detected as CL_TYPE_PNG/GIF rather
than as CL_TYPE_GRAPHICS. Target types now support up to 10
possible file types to make way for additional graphics types in
future releases.
* Fixed clamonacc's --fdpass option.
- Interprocess file descriptor passing for clamonacc was broken
since version 0.102.0 due to a bug introduced by the switch to
curl for communicating with clamd. On Linux, passing file
descriptors from one process to another is handled by the
kernel, so we reverted clamonacc to use standard system calls
for socket communication when fd passing is enabled.
* Fixed a clamonacc stack corruption issue on some systems when
using an older version of libcurl.
* Allow clamscan and clamdscan scans to proceed even if the
realpath lookup failed. This alleviates an issue on Windows
scanning files hosted on file- systems that do not support the
GetMappedFileNameW() API such as on ImDisk RAM-disks.
* Fixed freshclam --on-update-execute=EXIT_1 temporary directory
cleanup issue.
* clamd's log output and VirusEvent now provide the scan target's
file path instead of a file descriptor. The clamd socket API for
submitting a scan by FD-passing doesn't include a file path, this
feature works by looking up the file path by file descriptor.
This feature works on Mac and Linux but is not yet implemented
for other UNIX operating systems. FD-passing is not available for
Windows.
* Fixed an issue where freshclam database validation didn't work
correctly when run in daemon mode on Linux/Unix.

- Keep OBS from installing an existing clamav instance to scan the
sources, because this makes "make check" use the old library
instead of the just built one. This is only a workaround until
we found a way to keep libtool from adding libdir to rpath and
LD_LIBRARY_PATH of the binaries in the testsuite.

- Update to 0.103.0
* clamd can now reload the signature database without blocking
scanning. This multi-threaded database reload improvement was made
possible thanks to a community effort.
- Non-blocking database reloads are now the default behavior. Some
systems that are more constrained on RAM may need to disable
non-blocking reloads as it will temporarily consume two times as
much memory. We added a new clamd config option
ConcurrentDatabaseReload, which may be set to no.
* Dropped clamav-str-h.patch (no longer needed)

- Update to 0.102.4
* CVE-2020-3350: Fix a vulnerability wherein a malicious user could
replace a scan target's directory with a symlink to another path
to trick clamscan, clamdscan, or clamonacc into removing or moving
a different file (eg. a critical system file). The issue would
affect users that use the --move or --remove options for clamscan,
clamdscan, and clamonacc.
* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing
module in ClamAV 0.102.3 that could cause a Denial-of-Service
(DoS) condition. Improper bounds checking results in an
out-of-bounds read which could cause a crash. The previous fix for
this CVE in 0.102.3 was incomplete. This fix correctly resolves
the issue.
* CVE-2020-3481: Fix a vulnerability in the EGG archive module in
ClamAV 0.102.0 - 0.102.3 could cause a Denial-of-Service (DoS)
condition. Improper error handling may result in a crash due to a
NULL pointer dereference. This vulnerability is mitigated for
those using the official ClamAV signature databases because the
file type signatures in daily.cvd will not enable the EGG archive
parser in versions affected by the vulnerability.

* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing
module in ClamAV 0.102.2 that could cause a Denial-of-Service (DoS)
condition. Improper bounds checking of an unsigned variable results
in an out-of-bounds read which causes a crash.
* CVE-2020-3341: Fix a vulnerability in the PDF parsing module in
ClamAV 0.101 - 0.102.2 that could cause a Denial-of-Service (DoS)
condition. Improper size checking of a buffer used to initialize AES
decryption routines results in an out-of-bounds read which may cause
a crash.
* Fix "Attempt to allocate 0 bytes" error when parsing some PDF
documents.
* Fix a couple of minor memory leaks.
* Updated libclamunrar to UnRAR 5.9.2.

* CVE-2020-3123: A denial-of-service (DoS) condition may occur when
using the optional credit card data-loss-prevention (DLP) feature.
Improper bounds checking of an unsigned variable resulted in an
out-of-bounds read, which causes a crash.
* Significantly improved the scan speed of PDF files on Windows.
* Re-applied a fix to alleviate file access issues when scanning RAR
files in downstream projects that use libclamav where the scanning
engine is operating in a low-privilege process. This bug was originally
fixed in 0.101.2 and the fix was mistakenly omitted from 0.102.0.
* Fixed an issue where freshclam failed to update if the database version
downloaded is one version older than advertised. This situation may
occur after a new database version is published. The issue affected
users downloading the whole CVD database file.
* Changed the default freshclam ReceiveTimeout setting to 0 (infinite).
The ReceiveTimeout had caused needless database update failures for
users with slower internet connections.
* Correctly display the number of kilobytes (KiB) in progress bar and
reduced the size of the progress bar to accommodate 80-character width
terminals.
* Fixed an issue where running freshclam manually causes a daemonized
freshclam process to fail when it updates because the manual instance
deletes the temporary download directory. The freshclam temporary files
will now download to a unique directory created at the time of an update
instead of using a hardcoded directory created/destroyed at the program
start/exit.
* Fix for freshclam's OnOutdatedExecute config option.
* Fixes a memory leak in the error condition handling for the email
parser.
* Improved bound checking and error handling in ARJ archive parser.
* Improved error handling in PDF parser.
* Fix for memory leak in byte-compare signature handler.

* CVE-2019-15961: A Denial-of-Service (DoS) vulnerability may
occur when scanning a specially crafted email file as a result
of excessively long scan times. The issue is resolved by
implementing several maximums in parsing MIME messages and by
optimizing use of memory allocation.
* Build system fixes to build clamav-milter, to correctly link
with libxml2 when detected, and to correctly detect fanotify
for on-access scanning feature support.
* Signature load time is significantly reduced by changing to a
more efficient algorithm for loading signature patterns and
allocating the AC trie. Patch courtesy of Alberto Wu.
* Introduced a new configure option to statically link libjson-c
with libclamav. Static linking with libjson is highly
recommended to prevent crashes in applications that use
libclamav alongside another JSON parsing library.
* Null-dereference fix in email parser when using the
--gen-json metadata option.
* Fixes for Authenticode parsing and certificate signature
(.crb database) bugs.
- dropped clamav-fix_building_milter.patch (upstreamed)
- update to 0.102.0
* The On-Access Scanning feature has been migrated out of clamd
and into a brand new utility named clamonacc. This utility is
similar to clamdscan and clamav-milter in that it acts as a
client to clamd. This separation from clamd means that clamd no
longer needs to run with root privileges while scanning potentially
malicious files. Instead, clamd may drop privileges to run under an
account that does not have super-user. In addition to improving the
security posture of running clamd with On-Access enabled, this
update fixed a few outstanding defects:
- On-Access scanning for created and moved files (Extra-Scanning)
is fixed.
- VirusEvent for On-Access scans is fixed.
- With clamonacc, it is now possible to copy, move, or remove a
file if the scan triggered an alert, just like with clamdscan.
* The freshclam database update utility has undergone a significant
update. This includes:
- Added support for HTTPS.
- Support for database mirrors hosted on ports other than 80.
- Removal of the mirror management feature (mirrors.dat).
- An all new libfreshclam library API.
- created new subpackage libfreshclam2
- dropped clamav-max_patch.patch (upstreamed)

An out-of-bounds heap read condition may occur when scanning PE files
(i.e. Windows EXE and DLL files) that have been packed using Aspack as a
result of inadequate bound-checking.
* CVE-2019-1788:
An out-of-bounds heap write condition may occur when scanning OLE2 files
such as Microsoft Office 97-2003 documents. The invalid write happens when
an invalid pointer is mistakenly used to initialize a 32bit integer to
zero. This is likely to crash the application.
