    Synopsis
    ========

    Several serious vulnerabilities have been found in CVS, which may allow
    an attacker to remotely compromise a CVS server or cause a DoS.

    Background
    ==========

    CVS (Concurrent Versions System) is an open-source network-transparent
    version control system. It contains both a client utility and a server.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-util/cvs < 1.11.18-r1 >= 1.11.18-r1

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

    Alen Zukich has discovered several serious security issues in CVS,
    including at least one buffer overflow (CAN-2005-0753), memory leaks
    and a NULL pointer dereferencing error.

    Impact
    ======

    An attacker could exploit these vulnerabilities to cause a Denial of
    Service or execute arbitrary code with the permissions of the CVS
    pserver or the authenticated user (depending on the connection method
    used).

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All CVS users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-util/cvs-1.11.18-r1"
