Official Description
The OLE2 parser in Clam AntiVirus (ClamAV) allows remote attackers to cause a denial of service (resource consumption) via an OLE2 file with (1) a large property size or (2) a loop in the FAT file block chain that triggers an infinite loop, as demonstrated via a crafted DOC file.
Technical Analysis
CVE-2007-2650 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
