Synopsis
========

Multiple vulnerabilities in the AMD64 x86 emulation Qt library may lead
to the remote execution of arbitrary code in Qt applications.

Background
==========

Qt is a cross-platform GUI framework, which is used e.g. by KDE. The
AMD64 x86 emulation Qt library packages Qt libraries for 32bit x86
emulation on AMD64.

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

    -------------------------------------------------------------------
     Package                /    Vulnerable    /            Unaffected
    -------------------------------------------------------------------
  1  emul-linux-x86-qtlibs      < 20071114-r2           >= 20071114-r2
    -------------------------------------------------------------------
     # Package 1 only applies to AMD64 users.

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

The Qt versions used by the AMD64 x86 emulation Qt libraries were
vulnerable to several flaws (GLSA 200708-16, GLSA 200710-28)

Impact
======

An attacker could trigger one of the vulnerabilities by causing a Qt
application to parse specially crafted text or Unicode strings, which
may lead to the execution of arbitrary code with the privileges of the
user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All AMD64 x86 emulation Qt library users should upgrade to the latest
version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/emul-linux-x86-qtlibs-20071114-r2"
