Technical description

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.

Remediation

Check the references section for vendor advisories and patches from rarlab. Update winrar to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
