GLSA-201204-02 : InspIRCd: Arbitrary code execution
High Nessus Plugin ID 59618
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201204-02 (InspIRCd: Arbitrary code execution)
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.
SolutionAll InspIRCd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-irc/inspircd-2.0.5-r1'
