GLSA-202311-06 : multipath-tools: Multiple Vulnerabilities

high Nessus Plugin ID 186296

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202311-06 (multipath-tools: Multiple Vulnerabilities)

 - 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-2022-41973)

 - 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. (CVE-2022-41974)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

All multipath-tools users should upgrade to the latest version:

 # emerge --sync # emerge --ask --oneshot --verbose >=sys-fs/multipath-tools-0.9.3
