**Name of the Vulnerable Software and Affected Versions** Irssi versions 1.3.x through 1.4.3 **Description** The issue is caused by a use-after-free due to the use of a stale special collector reference. This occurs when the printing of a non-formatted line is concurrent with the printing of a formatted line. **Recommendations** For Irssi versions 1.3.x through 1.4.3, update to version 1.4.4 or later to resolve the issue.
