Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Clam AntiVirus (ClamAV) versions 0.102.0 through 0.102.3

Description A vulnerability in the EGG archive parsing module could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The issue is due to a null pointer dereference. An attacker could exploit this by sending a crafted EGG file to an affected device, potentially causing the ClamAV scanning process to crash.

Recommendations For versions 0.102.0 through 0.102.3, update to a version outside of this range to resolve the issue. As a temporary workaround, consider restricting the processing of EGG files until a patch is available.
