Description
Florian Westphal discovered a buffer overflow caused by an integer underflow in the Lists_MakeMask() function of lists.c.
Impact
A remote attacker can exploit this buffer overflow to crash the ngIRCd daemon and possibly execute arbitrary code with the rights of the ngIRCd daemon process.
Workaround
There is no known workaround at this time.
Resolution
