    Synopsis
    ========

    Qpopper contains two vulnerabilities allowing an attacker to overwrite
    arbitrary files and create files with insecure permissions.

    Background
    ==========

    Qpopper is a widely used server for the POP3 protocol.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-mail/qpopper < 4.0.5-r3 >= 4.0.5-r3

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

    Jens Steube discovered that Qpopper doesn't drop privileges to process
    local files from normal users (CAN-2005-1151). The upstream developers
    discovered that Qpopper can be forced to create group or world
    writeable files (CAN-2005-1152).

    Impact
    ======

    A malicious local attacker could exploit Qpopper to overwrite arbitrary
    files as root or create new files which are group or world writeable.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Qpopper users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-mail/qpopper-4.0.5-r3"
