Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 / 23.04 : TeX Live vulnerability (USN-6115-1)

high Nessus Plugin ID 176478


The remote Ubuntu host is missing a security update.


The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 / 23.04 host has packages installed that are affected by a vulnerability as referenced in the USN-6115-1 advisory.

- LuaTeX before 1.17.0 allows execution of arbitrary shell commands when compiling a TeX file obtained from an untrusted source. This occurs because luatex-core.lua lets the original io.popen be accessed. This also affects TeX Live before 2023 r66984 and MiKTeX before 23.5. (CVE-2023-32700)

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


Update the affected packages.
