Summary

xz-utils vulnerability

Details

Harri K. Koskinen discovered that XZ Utils incorrectly handled the threaded xz decoder. If a user or automated system were tricked into processing an xz file, a remote attacker could use this issue to cause XZ Utils to crash, resulting in a denial of service, or possibly execute arbitrary code.
