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.
