Date: January 28, 2005

Synopsis
ngIRCd is vulnerable to a buffer overflow that can be used to crash the
daemon and possibly execute arbitrary code.
Background

Affected packages
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

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
