Synopsis
========

Multiple packages suffer from RUNPATH issues that may allow users in
the "portage" group to escalate privileges.

Background
==========

Perl is a stable, cross-platform programming language created by Larry
Wall. Qt-UnixODBC is an ODBC library for Qt. CMake is a cross-platform
build environment.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  dev-lang/perl          < 5.8.7-r1                     >= 5.8.7-r1
                                                          *>= 5.8.6-r6
  2  dev-db/qt-unixodbc     < 3.3.4-r1                     >= 3.3.4-r1
  3  dev-util/cmake         < 2.2.0-r1                     >= 2.2.0-r1
                                                          *>= 2.0.6-r1
    -------------------------------------------------------------------
     3 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

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

Some packages may introduce insecure paths into the list of directories
that are searched for libraries at runtime. Furthermore, packages
depending on the MakeMaker Perl module for build configuration may have
incorrectly copied the LD_RUN_PATH into the DT_RPATH.

Impact
======

A local attacker, who is a member of the "portage" group, could create
a malicious shared object in the Portage temporary build directory that
would be loaded at runtime by a dependent executable, potentially
resulting in privilege escalation.

Workaround
==========

Only grant "portage" group rights to trusted users.

Resolution
==========

All Perl users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-lang/perl

All Qt-UnixODBC users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-db/qt-unixodbc-3.3.4-r1"

All CMake users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose dev-util/cmake
