CVE-2012-5573

Published Jan 1, 2013 torproject CWE-399

Overview

CVE-2012-5573 is a known-severity vulnerability affecting torproject tor. It was published on January 1, 2013.

Technical Description

The connection_edge_process_relay_cell function in or/relay.c in Tor before 0.2.3.25 maintains circuits even if an unexpected SENDME cell arrives, which might allow remote attackers to cause a denial of service (memory consumption or excessive cell reception rate) or bypass intended flow-control restrictions via a RELAY_COMMAND_SENDME command.

Remediation

Check the references section for vendor advisories and patches from torproject. Update tor 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.
