Ubuntu 20.04 LTS / 22.04 LTS / 23.10 : TeX Live vulnerabilities (USN-6695-1)

critical Nessus Plugin ID 192119


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


The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6695-1 advisory.

- In axohelp.c before 1.3 in axohelp in axodraw2 before 2.1.1b, as distributed in TeXLive and other collections, sprintf is mishandled. (CVE-2019-18604)

- 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. (CVE-2023-32668)

- texlive-bin commit c515e was discovered to contain heap buffer overflow via the function ttfLoadHDMX:ttfdump. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted TTF file. (CVE-2024-25262)

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