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 | Architecture(s) |
---|---|---|---|
net-irc/inspircd | < 2.0.5-r1 | >= 2.0.5-r1 | All supported architectures |
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"
