Official Description
arclib.dll before 7.3.0.9 in CA Anti-Virus (formerly eTrust Antivirus) 8 and certain other CA products allows remote attackers to cause a denial of service (infinite loop and loss of antivirus functionality) via an invalid "previous listing chunk number" field in a CHM file.
Technical Analysis
CVE-2007-3875 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.
