"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by a vulnerability as referenced in the
ALINUX3-SA-2022:0177 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
