Synopsis ========
A heap-based buffer overflow in InspIRCd may allow execution of arbitrary code.
Background ==========
InspIRCd (Inspire IRCd) is a modular C++ IRC daemon
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/inspircd < 2.0.5-r1 >= 2.0.5-r1
Description ===========
A vulnerability in InspIRCd allows DNS compression features to control the number of overflowed bytes sent to the heap-based buffer "res[]" in dns.cpp.
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All InspIRCd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/inspircd-2.0.5-r1"
