Overview

This vulnerability has a CVSS 2.0 base score of 5.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Buffer overflow in the "Add to archive" command in WinRAR 3.51 allows user-assisted attackers to cause a denial of service (crash) and possibly execute arbitrary code by tricking the user into adding a file whose filename contains a non-default code page and non-ANSI characters, as demonstrated using a Chinese filename, possibly due to buffer expansion when using the WideCharToMultiByte API. NOTE: it is not clear whether this problem can be exploited for code execution. If not, then perhaps the user-assisted nature of the attack should exclude the issue from inclusion in CVE.

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.
