**Name of the Vulnerable Software and Affected Versions** ClamAV (affected versions not specified) **Description** An issue exists in the ALZ file format parser where improper boundary checks for content during scanning can lead to an out-of-bounds buffer write. A remote, unauthenticated attacker can exploit this by submitting a specially crafted ALZ file, causing memory corruption. This may result in the termination of the scanning process, leading to a Denial of Service (DoS) condition, or potentially other expanded impacts. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
