Synopsis
The remote Amazon Linux 2023 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-126 advisory.A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, exploited alone or in conjunction with CVE-2022-41973. Local users that are able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This issue occurs because an attacker can repeat a keyword, which is mishandled when arithmetic ADD is used instead of bitwise OR. This could lead to local privilege escalation to root. (CVE-2022-3787)
A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, in conjunction with CVE-2022-41974. Local users that are able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which may 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)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
