Bug(s): #79705
ID: 200501-40

Synopsis

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

Background

ngIRCd is a free open source daemon for Internet Relay Chat (IRC).

Affected Packages

Package: net-irc/ngircd
Vulnerable: < 0.8.2

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
