Synopsis
A buffer overflow in InspIRCd allows remote attackers to cause a Denial of Service.Background
InspIRCd (Inspire IRCd) is a modular C++ IRC daemon.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
net-irc/inspircd | < 1.1.19 | >= 1.1.19 | All supported architectures |
Description
The "namesx" and "uhnames" modules do not properly validate network input, leading to a buffer overflow.
Impact
A remote attacker can send specially crafted IRC commands to the server, causing a Denial of Service.
Workaround
Unload the "uhnames" module in the InspIRCd configuration.
Resolution
All InspIRCd users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/inspircd-1.1.19"
