Background

InspIRCd (Inspire IRCd) is a modular C++ IRC daemon

Affected Packages

Package: net-irc/inspircd
Vulnerable: < 2.0.5-r1
Unaffected: >= 2.0.5-r1
Architectures: All supported architectures


Description

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:
