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.

Notes

Author	Note
sbeattie	looks like triggerable asserts that cause a DoS
