CVE-2012-4419  (opens in a new tab)

How to fix?

Upgrade Ubuntu:14.10 tor to version 0.2.3.22-rc-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream tor package and not the tor package as distributed by Ubuntu. See How to fix? for Ubuntu:14.10 relevant fixed versions and status.

The compare_tor_addr_to_addr_policy function in or/policies.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.21-rc, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a zero-valued port field that is not properly handled during policy comparison.
