Clam Anti-Virus ClamAV UPX Compressed File Heap Buffer Overflow Vulnerability
ClamAV is prone to a heap buffer-overflow vulnerability. This issue is due to the application's failure to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer. This issue occurs when the application attempts to handle compressed UPX files. Exploitation of this issue could allow attacker-supplied machine code to be executed in the context of the affected application. The issue would occur when the malformed file is scanned manually or automatically in deployments such as email gateways. |
