CVE-2007-2845: Heap-based buffer overflow in the CAB unpacker in avast!

Heap-based buffer overflow in the CAB unpacker in avast! Anti-Virus Managed Client before 4.7.700 allows user-assisted remote attackers to execute arbitrary code via a crafted CAB archive, resulting from an "integer cast around".

Security readout for executives and security teams

CVE-2007-2845 is an old Avast Managed Client issue where a malformed CAB archive could crash unsafe parsing and allow arbitrary code execution. The attacker would need a user or system workflow to process the crafted archive. The main risk is legacy antivirus infrastructure still running versions before 4.7.700. Exposure is likely limited to organizations with legacy avast! Anti-Virus Managed Client installations before 4.7.700 or archived systems that still scan CAB files with that engine. Modern Avast products are not identified as affected in the provided sources. Treat this as high priority only if legacy Avast Managed Client remains in use. For most environments, the immediate task is inventory validation, not emergency response, because the vulnerability is from 2007 and no active exploitation evidence is provided. Mitigation focus: Inventory Avast Managed Client versions and identify any releases before 4.7.700.; Upgrade affected clients to 4.7.700 or a vendor-supported replacement.; Restrict processing of untrusted CAB archives on legacy systems..
