Echo: libxml2: security update to 2.12.7+dfsg+really2.9.14-2.1+deb13u2+e6

medium Tenable Self-Hosted Container Security Plugin ID 461288

Description

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

 - A flaw was identified in the interactive shell of the xmllint utility, part of the libxml2 project, where
 memory allocated for user input is not properly released under certain conditions. When a user submits
 input consisting only of whitespace, the program skips command execution but fails to free the allocated
 buffer. Repeating this action causes memory to continuously accumulate. Over time, this can exhaust system
 memory and terminate the xmllint process, creating a denial-of-service condition on the local system.
 (CVE-2026-1757)

Solution

Update the libxml2 library and its related packages to version 2.12.7+dfsg+really2.9.14-2.1+deb13u2+e6 or later.
