|Gentoo Linux Security Advisory
Title: InspIRCd: Arbitrary code execution (GLSA 201204-02)
Date: April 10, 2012
A heap-based buffer overflow in InspIRCd may allow execution of
InspIRCd (Inspire IRCd) is a modular C++ IRC daemon
Vulnerable: < 2.0.5-r1
Unaffected: >= 2.0.5-r1
Architectures: All supported architectures
A vulnerability in InspIRCd allows DNS compression features to control
the number of overflowed bytes sent to the heap-based buffer "res" in
A remote attacker could send specially crafted DNS responses, possibly
resulting in execution of arbitrary code with the privileges of the
process or a Denial of Service condition.
There is no known workaround at this time.
All InspIRCd users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/inspircd-2.0.5-r1"
