ClamAV Vulnerabilities Affecting Cisco Products: July 2026

view advisory published 2026-07-01

Multiple vulnerabilities in ClamAV could allow a remote attacker to cause a denial of service (DoS) condition, interrupting scanning operations. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. For additional information on these vulnerabilities in ClamAV, see the ClamAV blog ["https://blog.clamav.net/2026/07/clamav-153-and-145-security-patch.html"]. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. Notes: The Security Impact Rating (SIR) for these vulnerabilities is High for Windows-based platforms only because those platforms run the ClamAV scanning process in a privileged security context. The platforms that are highly impacted include Cisco Secure Endpoint Connector for Windows. The SIR for these vulnerabilities is Medium on other platforms, including Linux and Mac platforms, because those platforms run the ClamAV scanning process in a lower-privileged security context. The affected platforms include Secure Endpoint Connector for Linux and Mac. Cisco Secure Endpoint Private Cloud itself is not impacted by these vulnerabilities. However, the Cisco Secure Endpoint Connector software that is distributed from the device is impacted.
