Description Vincent Danen 2012-03-22 21:21:30 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2012-1458 to
the following vulnerability:

Name: CVE-2012-1458
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-1458
Assigned: 20120229
Reference: BUGTRAQ:20120319 Evasion attacks expoliting file-parsing vulnerabilities in antivirus products
Reference: http://www.securityfocus.com/archive/1/522005
Reference: http://www.ieee-security.org/TC/SP2012/program.html

The Microsoft CHM file parser in ClamAV 0.96.4 and Sophos Anti-Virus
4.61.0 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.

Upstream has no further information as of yet; the report indicates the flaw is in 0.96.4, but the current upstream version is 0.97.4, so it's unknown whether these flaws are still present.
