Description Jan Lieskovsky 2010-09-05 16:09:48 UTC

A denial of service flaw was found in the way Squid proxy caching
server internally processed NULL buffers. A remote, trusted client
could use this flaw to cause squid daemon crash (dereference NULL pointer)
when processing specially-crafted request.
