CVE-2010-2812: Input Validation
First published: Mon Aug 09 2010(Updated: )
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].
