CWE-121  (opens in a new tab)

How to fix?

Upgrade Echo:latest libxml2 to version 2.9.14+dfsg-1.3~deb12u3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2 package and not the libxml2 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A flaw was found in the interactive shell of the xmllint command-line tool, used for parsing XML files. When a user inputs an overly long command, the program does not check the input size properly, which can cause it to crash. This issue might allow attackers to run harmful code in rare configurations without modern protections.
