Multiple vulnerabilities have been identified in 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 an integer overflow error within the "cli_scanpe()" [libclamav/pe.c] function when parsing PE files packed with the MEW packer, 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 off-by-one buffer overflow error in the MS-ZIP decompression code, which could be exploited to crash a vulnerable application or execute arbitrary code.
The third issue is caused by an unspecified bzlib error.
