Ubuntu 22.04 LTS : libnfs vulnerability (USN-9008-1)

high Nessus Plugin ID 378017

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-9008-1 advisory.

It was discovered that libnfs did not properly enforce the maximum size bound during ZDR decoding, resulting in an out-of-bounds write. An attacker could possibly use this issue to cause libnfs to crash, resulting in a denial of service, or execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected libnfs-utils and / or libnfs13 packages.
