Descriptions

LuaTeX before 1.17.0 allows a document (compiled with the default settings) to make arbitrary network requests. This occurs because full access to the socket library is permitted by default, as stated in the documentation. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5.

It was discovered that TeX Live incorrectly handled certain memory operations in the embedded axodraw2 tool. An attacker could possibly use this issue to cause TeX Live to crash, resulting in a denial of service. This issue only affected Ubuntu 20.04 LTS. 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 20.04 LTS, and Ubuntu 22.04 LTS.
