FKIE_CVE-2012-1458

Vulnerability from fkie_nvd - Published: 2012-03-21 10:11 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
