- update to 2.0.10
- Fix compiling on Alpine Linux.
- Stop printf compiler warning on Alpine Linux due to rlim_t.
- manpage cosmetic.
- Fix removing snmpd read threads when snmpd becomes unavailable.
- Update to support libipset version 7.
- Use ipset_printf for ipset messages so can go to log.
- When opening files for write, ensure files can only be read by
root. Issue #1048 referred to CVE-2018-19046 regarding files
used for debugging purposes could potentially be read by non
root users. This commit ensures that such log files cannot be
opened by non root users.
- Disable fopen_safe() append mode by default If a non privileged
user creates /tmp/keepalived.log and has it open for read (e.g.
tail -f), then even though keepalived will change the owner to
root and remove all read/write permissions from non owners, the
application which already has the file open will be able to
read the added log entries. Accordingly, opening a file in
append mode is disabled by default, and only enabled if
--enable-smtp-alert-debug or --enable-log-file (which are
debugging options and unset by default) are enabled. This
should further alleviate security concerns related to
CVE-2018-19046.
- vrrp: add support to constant time memcmp. Just an update to
use best practise security design pattern. While comparing
password or hmac you need to ensure comparison function is time
constant in order to figth against any timing attacks. We turn
off potential compiler optimizations for this particular
function to avoid any short circuit.
- Make sure a non privileged user cannot read keepalived file
output Ensure that when a file such as /tmp/keepalived.data is
written, no non privileged can have a previous version of that
file already open, thereby allowing them to read the data.
This should fully resolve CVE-2018-19046.
