Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS : TeX Live vulnerabilities (USN-7985-1)

high Nessus Plugin ID 297276

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-7985-1 advisory.

Shin Ando discovered that the Xpdf toolkit embedded in TeX Live incorrectly handled memory when decoding certain data streams. An attacker could possibly use this issue to cause TeX Live to crash, resulting in a denial of service, or execute arbitrary code. This issue only affected Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-24106, CVE-2022-24107)

It was discovered that TeX Live allowed documents to make arbitrary network requests. If a user or automated system were tricked into opening a specially crafted document, a remote attacker could possibly use this issue to exfiltrate sensitive information, or perform other network-related attacks. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2023-32668)

It was discovered that TeX Live incorrectly handled certain TrueType fonts. If a user or automated system were tricked into opening a specially crafted TrueType font, a remote attacker could use this issue to cause TeX Live to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2024-25262)

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

Update the affected packages.
