GLSA-200501-40 : ngIRCd: Buffer overflow
High Nessus Plugin ID 16431
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200501-40 (ngIRCd: Buffer overflow)
Florian Westphal discovered a buffer overflow caused by an integer underflow in the Lists_MakeMask() function of lists.c.
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.
There is no known workaround at this time.
SolutionAll ngIRCd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/ngIRCd-0.8.2'
