Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7001-1 advisory.

 Shang-Hung Wan discovered that Expat, contained within the xmltok library, did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2024-45490)

 Shang-Hung Wan discovered that Expat, contained within the xmltok library, did not properly handle the potential for an integer overflow on 32-bit platforms. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2024-45491)

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.

Solution
