Amazon Linux 2023 : device-mapper-multipath, device-mapper-multipath-devel, device-mapper-multipath-libs (ALAS2023-2023-126)

high Nessus Plugin ID 173185


The remote Amazon Linux 2023 host is missing a security update.


It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-126 advisory.

- 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)

- device-mapper-multipath: Regression of CVE-2022-41974 fix in Red Hat Enterprise Linux (CVE-2022-3787)

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


Run 'dnf update device-mapper-multipath --releasever=2023.0.20230308' to update your system.
