Comment 1 Kristian Fiskerstrand (RETIRED) gentoo-dev 2014-12-11 12:18:47 UTC
From $[URL}:
When handling a WebSocket frame the res_http_websocket module dynamically changes the size of the memory used to allow the provided payload to fit. If a payload length of zero was received the code would incorrectly attempt to resize to zero. This operation would succeed and end up freeing the memory but be treated as a failure. When the session was subsequently torn down this memory would get freed yet again causing a crash.

Arches, please test & mark stable:

Please test with USE="samples" and take the daemon through three stop/start cycles.

Changing rating to B3, for some reason I didn't remember this is indeed a stable package.
