A heap-based buffer overflow in InspIRCd may allow execution of arbitrary code.
|Package||net-irc/inspircd on all architectures|
|Affected versions||< 2.0.5-r1|
|Unaffected versions||>= 2.0.5-r1|
InspIRCd (Inspire IRCd) is a modular C++ IRC daemon
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.
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"
