High

Base vector

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

Name of the Vulnerable Software and Affected Versions Clam AntiVirus versions 0.103.4 and prior versions Clam AntiVirus version 0.104.1

Description The issue is related to insufficient input validation in the OOXML parsing module. An attacker could exploit this by sending a specially crafted OOXML file to an affected device, potentially causing a denial of service condition due to improper checks that may result in an invalid pointer read. This could allow the attacker to crash the ClamAV scanning process.

Recommendations For Clam AntiVirus versions 0.103.4 and prior versions, update to a version that includes the fix for this issue. For Clam AntiVirus version 0.104.1, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting the processing of OOXML files until a patch is available.
