Cisco has recently issued a warning about seven ClamAV flaws that affect its Secure Endpoint Connector products, which are used to scan files and emails for malware. The company states that two of these vulnerabilities have public Proof-of-Concept (PoC) code available, which could be exploited by unauthenticated attackers to cause a denial of service (DoS) condition on affected devices.
The affected ClamAV versions are 1.5.4, with the most severe flaw having a CVSS score of 7.5 and being classified as High-risk on Windows due to its elevated privilege execution. The vulnerability is caused by improper memory handling when processing content in zip files during scanning, which may result in an out-of-bounds write condition.
