CVE-2005-4620: RARLAB WinRAR

Medium severity, CVSS 4.6. EPSS: 1.5% chance of exploitation in the next 30 days.

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.

• RARLAB WinRAR: version 2.90 only; version 3.0.0 only; version 3.10 only; version 3.10_beta3 only; version 3.10_beta5 only; version 3.11 only; …
