    Synopsis
    ========

    An information disclosure vulnerability in InspIRCd may allow remote
    attackers to obtain sensitive information.

    Background
    ==========

    InspIRCd is a modular Internet Relay Chat (IRC) server written in C++
    which was created from scratch to be stable, modern and lightweight.

    Affected packages
    =================

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 net-irc/inspircd < 3.10.0 >= 3.10.0

    Description
    ===========

    InspIRCd incorrectly handled malformed PONG messages, resulting in
    access of freed memory.

    Impact
    ======

    A remote attacker could send crafted packets to the server, possibly
    allowing them to obtain sensitive information.

    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-3.10.0"
