DESCRIPTION:
Two vulnerabilities have been reported in Tor, which can be exploited
by malicious people to cause a DoS (Denial of Service).

1) An assertion failure within the "tor_timegm()" function when
handling time information within a directory object can be exploited
to cause a crash.

2) An assertion failure within the
"compare_tor_addr_to_addr_policy()" function when handling certain
port values can be exploited to crash directory authorities.

The vulnerabilities are reported in versions prior to 0.2.2.39.

SOLUTION:
Update to version 0.2.2.39.

PROVIDED AND/OR DISCOVERED BY:
