high Tenable Cloud Security Plugin ID 455142

Description

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

 - In xinclude in libxml2 before 2.15.4, xmlXIncludeProcess and xmlXIncludeProcessTree do not propagate
 parseFlags. This has security relevance for, for example, the XML_PARSE_NONET flag, if (without it) a
 custom resource loader accesses the internet and triggers XML external entity injection, SSRF, or a denial
 of service (e.g., for an attacker-controlled internet resource that is intentionally slow).
 (CVE-2026-86144)

Solution

Update the libxml2 library and its related packages to version 2.12.7+dfsg+really2.9.14-2.1+deb13u3+e1 or later.
