    Synopsis
    ========

    A buffer overflow has been reported in Convert-UUlib, potentially
    resulting in the execution of arbitrary code.

    Background
    ==========

    Convert-UUlib provides a Perl interface to the uulib library, allowing
    Perl applications to access data encoded in a variety of formats.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-perl/Convert-UUlib < 1.051 >= 1.051

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

    A vulnerability has been reported in Convert-UUlib where a malformed
    parameter can be provided by an attacker allowing a read operation to
    overflow a buffer. The vendor credits Mark Martinec and Robert Lewis
    with the discovery.

    Impact
    ======

    Successful exploitation would permit an attacker to run arbitrary code
    with the privileges of the user running the Perl application.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Convert-UUlib users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-perl/Convert-UUlib-1.051"
