2012-10-25Fold in changelog item; draft blurb for 0.2.4.5-alphaNick Mathewson
2012-10-23Fix a remotely triggerable assertion failure (CVE-2012-2250)Nick Mathewson
If we completed the handshake for the v2 link protocol but wound up negotiating the wong protocol version, we'd become so confused about what part of the handshake we were in that we'd promptly die with an assertion. This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha. All servers running that version or later should really upgrade. Bug and fix from "some guy from France." I tweaked his code slightly to make it log the IP of the offending node, and to forward-port it to 0.2.4.
