Description Jan Lieskovsky 2012-01-24 14:11:39 UTC
A stack-based buffer overflow flaw was found in the way Bip, the IRC proxy, performed handling of IRC servers connection events (the number of file descriptors being used by that connection was not compared against predefined maximum number of file descriptors in 'fd_set'). When number of open file descriptors was greater or equal to FD_SETSIZE an attacker could use this flaw to cause bip daemon crash.
