Synopsis
========
The AMD64 x86 emulation Qt library makes use of an insecure version of
the Qt library, potentially allowing for the remote execution of
arbitrary code.
Background
==========
The AMD64 x86 emulation Qt library for AMD64 emulates the x86 (32-bit)
Qt library on the AMD64 (64-bit) architecture.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 emul-linux-x86-qtlibs < 10.0 >= 10.0
Description
===========
An integer overflow flaw has been found in the pixmap handling of Qt,
making the AMD64 x86 emulation Qt library vulnerable as well.
Impact
======
By enticing a user to open a specially crafted pixmap image in an
application using the AMD64 x86 emulation Qt library, a remote attacker
could cause an application crash or the remote execution of arbitrary
code with the rights 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-10.0"
