clamav: multiple vulnerabilities

The TAR file parser in ClamAV 0.96.4 allows remote attackers to bypass malware detection via a TAR archive entry with a length field that exceeds the total TAR file size. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different TAR parser implementations (CVE-2012-1457).

The Microsoft CHM file parser in ClamAV 0.96.4 allows remote attackers to bypass malware detection via a crafted reset interval in the LZXC header of a CHM file. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different CHM parser implementations (CVE-2012-1458).

The TAR file parser in ClamAV 0.96.4 allows remote attackers to bypass malware detection via a TAR archive entry with a length field corresponding to that entire entry, plus part of the header of the next entry. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different TAR parser implementations (CVE-2012-1459).
