Description Vincent Danen 2010-08-09 21:44:43 UTC
An out-of-range flaw was found in znc where if it received a "PING" from a client without an argument, std::string would throw a std::out_of_range exception which killed znc.  This is fixed in subversion [1].

Some unsafe substr() calls were fixed as well.  These are of lesser impact because a valid login is required in order to cause a std::out_of_range exception.  This is also fixed in subversion [2].
