**Name of the Vulnerable Software and Affected Versions** wall versions 10.20 through 11.11 **Description** A buffer overflow issue in the wall utility may allow local users to execute arbitrary code by calling wall with a large file as an argument. **Recommendations** For versions 10.20 through 11.11, consider restricting access to the wall utility until a patch is available. As a temporary workaround, avoid using the wall utility with large files as arguments to minimize the risk of exploitation.
