Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6694-1 advisory.

 It was discovered that Expat could be made to consume large amounts of resources. If a user or automated system were tricked into processing specially crafted input, an attacker could possibly use this issue to cause a denial of service. (CVE-2023-52425, CVE-2024-28757)

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

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