Vulnerability from fkie_nvd - Published: 2007-04-16 21:19 - Updated: 2026-06-16 22:38
Severity
Summary
Integer signedness error in the (1) cab_unstore and (2) cab_extract functions in libclamav/cab.c in Clam AntiVirus (ClamAV) before 0.90.2 allow remote attackers to execute arbitrary code via a crafted CHM file that contains a negative integer, which passes a signed comparison and leads to a stack-based buffer overflow.
