Echo: texlive-bin: security update to 2024.20240313.70630+ds-6+e1

medium Tenable Self-Hosted Container Security Plugin ID 460862

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - The SyncTeX parser (synctex_parser.c) shipped with TeX Live and embedded by downstream consumers such as
 GNOME Evince contains a heap use-after-free vulnerability that allows attackers to crash applications or
 potentially execute arbitrary code by supplying a malformed .synctex or .synctex.gz file. A malformed
 SyncTeX file can construct a ref node with a NULL parent pointer, causing the replacement routine to fail
 to detach the node from its sibling chain, which triggers recursive freeing of live tree nodes and leaves
 dangling pointers that are later accessed by the parser during document load. (CVE-2026-63729)

Solution

Update the texlive-bin library and its related packages to version 2024.20240313.70630+ds-6+e1 or later.
