Description Vincent Danen 2011-05-16 22:20:41 UTC

A vulnerability in Tor was reported [1] that could allow a malicious remote attacker to cause a denial of service.  This vulnerability is due to a boundary error within the policy_summarize() function in src/or/policies.c which can be exploited to crash a Tor directory authority.

Upstream announced the release of 0.2.1.30 [2] that is noted to correct this flaw.
