Summary:

Several security issues were fixed in TeX Live.

Software Description:
- texlive-bin: Binaries for TeX Live

Details:

It was discovered that TeX Live incorrectly handled certain memory

This issue only affected Ubuntu 20.04 LTS. (CVE-2019-18604)

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

attacks. This issue only affected Ubuntu 20.04 LTS, and Ubuntu 22.04 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

crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2024-25262)
