Arch Linux: Denial of service (CVE-2025-6170)

A stack-based buffer overflow vulnerability exists in the command-parsing logic of the interactive shell in xmllint. An attacker can supply an overly long argument to any shell command, triggering an unbounded memory copy that overflows a fixed-size buffer on the stack. This leads to a reliable Denial of Service and could be leveraged for Arbitrary Code Execution on systems without exploit mitigations.
