Package : multipath-tools Version : 0.7.9-3+deb10u2 CVE ID : CVE-2022-41973 CVE-2022-41974 Debian Bug : 1022742

Multiple issues were found in multipath-tools, a tool-chain to manage disk multipath device maps, which may be used by local attackers to obtain root privileges or create a directories or overwrite files via symlink attacks.

Please note that the fix for CVE-2022-41973 involves switching from /dev/shm to systemd-tmpfiles (/run/multipath-tools).
If you have previously accesssed /dev/shm directly, please update your setup to the new path to facilitate this change.

CVE-2022-41973

multipath-tools 0.7.7 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited in conjunction with CVE-2022-41974.
Local users able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which could lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.

CVE-2022-41974

multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.

For Debian 10 buster, these problems have been fixed in version 0.7.9-3+deb10u2.

We recommend that you upgrade your multipath-tools packages.
