GLSA 200703-06: AMD64 x86 emulation Qt library: Integer overflow

http://security.gentoo.org/

Severity:	normal
Title:	AMD64 x86 emulation Qt library: Integer overflow
Date:	03/04/2007
Bugs:	#153704
ID:	200703-06

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	Architecture(s)
app-emulation/emul-linux-x86-qtlibs	< 10.0	>= 10.0	All supported architectures

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"
