Accepting request 863080 from home:kstreitova:branches:Base:System

- Update to 1.9.5.p1
  * Fixed a regression introduced in sudo 1.9.5 where the editor run
    by sudoedit was set-user-ID root unless SELinux RBAC was in use.
    The editor is now run with the user's real and effective user-IDs.
- News in 1.9.5
  * Fixed a crash introduced in 1.9.4 when running "sudo -i" as an
    unknown user.  This is related to but distinct from Bug #948.
  * If the "lecture_file" setting is enabled in sudoers, it must now
    refer to a regular file or a symbolic link to a regular file.
  * Fixed a potential use-after-free bug in sudo_logsrvd when the
    server shuts down if there are existing connections from clients
    that are only logging events and not session I/O data.
  * Fixed a buffer size mismatch when serializing the list of IP
    addresses for configured network interfaces.  This bug is not
    actually exploitable since the allocated buffer is large enough
    to hold the list of addresses.
  * If sudo is executed with a name other than "sudo" or "sudoedit",
    it will now fall back to "sudo" as the program name.  This affects
    warning, help and usage messages as well as the matching of Debug
    lines in the /etc/sudo.conf file.  Previously, it was possible
    for the invoking user to manipulate the program name by setting
    argv[0] to an arbitrary value when executing sudo.
  * Sudo now checks for failure when setting the close-on-exec flag
    on open file descriptors.  This should never fail but, if it
    were to, there is the possibility of a file descriptor leak to
    a child process (such as the command sudo runs).
  * Fixed CVE-2021-23239, a potential information leak in sudoedit
    that could be used to test for the existence of directories not
    normally accessible to the user in certain circumstances.  When
    creating a new file, sudoedit checks to make sure the parent

+    that could be used to test for the existence of directories not
+    normally accessible to the user in certain circumstances.  When
+    creating a new file, sudoedit checks to make sure the parent
+    directory of the new file exists before running the editor.
+    However, a race condition exists if the invoking user can replace
+    (or create) the parent directory.  If a symbolic link is created
+    in place of the parent directory, sudoedit will run the editor
+    as long as the target of the link exists.  If the target of the
+    link does not exist, an error message will be displayed.  The
+    race condition can be used to test for the existence of an
+    arbitrary directory.  However, it _cannot_ be used to write to
+    an arbitrary location.
+  * Fixed CVE-2021-23240, a flaw in the temporary file handling of
+    sudoedit's SELinux RBAC support.  On systems where SELinux is
+    enabled, a user with sudoedit permissions may be able to set the
+    owner of an arbitrary file to the user-ID of the target user.
+    On Linux kernels that support "protected symlinks", setting
+    /proc/sys/fs/protected_symlinks to 1 will prevent the bug from
+    being exploited.  For more information see
+    https://www.sudo.ws/alerts/sudoedit_selinux.html.
+  * Added writability checks for sudoedit when SELinux RBAC is in use.
+    This makes sudoedit behavior consistent regardless of whether
+    or not SELinux RBAC is in use.  Previously, the "sudoedit_checkdir"
+    setting had no effect for RBAC entries.
+  * A new sudoers option "selinux" can be used to disable sudo's
+    SELinux RBAC support.
+  * Quieted warnings from PVS Studio, clang analyzer, and cppcheck.
+    Added suppression annotations for PVS Studio false positives.
