CVE-2005-4620: Buffer overflow in WinRAR 3.50 and earlier allows local users to execute arbitrary code via a long command-...

Buffer overflow in WinRAR 3.50 and earlier allows local users to execute arbitrary code via a long command-line argument. NOTE: because this program executes with the privileges of the invoking user, and because remote programs do not normally have the ability to specify a command-line argument for this program, there may not be a typical attack vector for the issue that crosses privilege boundaries. Therefore this may not be a vulnerability.

Security readout for executives and security teams

This old WinRAR issue describes a buffer overflow triggered by an overly long startup argument. The public CVE notes it runs with the same privileges as the user who launches WinRAR, and may lack a normal path to cross privilege boundaries. Business urgency is low unless legacy WinRAR is still deployed in managed environments. Exposure is most likely on endpoints or servers still running WinRAR 3.50 or earlier. The source bundle has no structured affected CPEs, so validation should rely on software inventory and vendor guidance. Treat as low-priority legacy software hygiene unless old WinRAR versions remain deployed on shared or sensitive systems. The main value is reducing unsupported tooling and local execution risk, not responding to an active campaign. Mitigation focus: Identify and remove unsupported WinRAR 3.50 or earlier installations.; Check RARLAB guidance and change history for the relevant fixed version.; Upgrade WinRAR where vendor guidance confirms this issue is addressed..
