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 / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-irc/ngircd < 0.8.2 >= 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
=========
All ngIRCd users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/ngIRCd-0.8.2"
References
