CVE-2025-6170

Libxml2: stack buffer overflow in xmllint interactive shell command handling

State: Published
Severity: 2.5 Low
Published: Jun 16, 2025
Updated: Nov 2, 2026
Reserved: Jun 16, 2025

Description

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.
