Vulnerability Summary for CVE-2012-4922

Original release date:09/14/2012
Last revised:04/11/2013
Source: US-CERT/NIST

Overview

The tor_timegm function in common/util.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.22-rc, does not properly validate time values, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed directory object, a different vulnerability than CVE-2012-4419.
