    Synopsis
    ========

    The Gentoo Net-SNMP package may provide Perl modules containing an
    insecure DT_RPATH, potentially allowing privilege escalation.

    Background
    ==========

    Net-SNMP is a suite of applications used to implement the Simple
    Network Management Protocol.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-analyzer/net-snmp < 5.2.1.2-r1 >= 5.2.1.2-r1

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

    James Cloos reported that Perl modules from the Net-SNMP package look
    for libraries in an untrusted location. This is due to a flaw in the
    Gentoo package, and not the Net-SNMP suite.

    Impact
    ======

    A local attacker (member of the portage group) may be able to create a
    shared object that would be loaded by the Net-SNMP Perl modules,
    executing arbitrary code with the privileges of the user invoking the
    Perl script.

    Workaround
    ==========

    Limit group portage access to trusted users.

    Resolution
    ==========

    All Net-SNMP users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1.2-r1"

    Availability
    ============

    This GLSA and any updates to it are available for viewing at
    the Gentoo Security Website:

    confidentiality and security of our users machines is of utmost
    importance to us. Any security concerns should be addressed to
