Resolves ticket 15515.
+Changes in version 0.2.5.12 - 2015-04-06
+ Tor 0.2.5.12 backports two fixes from 0.2.6.7 for security issues that
+ could be used by an attacker to crash hidden services, or crash clients
+ visiting hidden services. Hidden services should upgrade as soon as
+ possible; clients should upgrade whenever packages become available.
+
+ This release also backports a simple improvement to make hidden
+ services a bit less vulnerable to denial-of-service attacks.
+
+ o Major bugfixes (security, hidden service):
+ - Fix an issue that would allow a malicious client to trigger an
+ assertion failure and halt a hidden service. Fixes bug 15600;
+ bugfix on 0.2.1.6-alpha. Reported by "disgleirio".
+ - Fix a bug that could cause a client to crash with an assertion
+ failure when parsing a malformed hidden service descriptor. Fixes
+ bug 15601; bugfix on 0.2.1.5-alpha. Found by "DonnchaC".
+
+ o Minor features (DoS-resistance, hidden service):
+ - Introduction points no longer allow multiple INTRODUCE1 cells to
+ arrive on the same circuit. This should make it more expensive for
+ attackers to overwhelm hidden services with introductions.
+ Resolves ticket 15515.
