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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
