Technical Description

Multiple vulnerabilities have been identified in Clam AntiVirus (ClamAV), which could be exploited by remote attackers or malware to cause a denial of service or take complete control of an affected system.

The first issue is caused by a heap corruption error in the "libclamav/mew.c" file when processing certain files, which could be exploited by attackers to execute arbitrary commands by tricking a vulnerable application into scanning a specially crafted file.

The second vulnerability is caused by an integer overflow error in the "libclamav/pe.c" file when handling certain PE files, which could be exploited to crash a vulnerable application or execute arbitrary code.
