- 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.
