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.

2. Impact Information

Background

The AMD64 x86 emulation Qt library for AMD64 emulates the x86 (32-bit) Qt library on the AMD64 (64-bit) architecture.

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-qtlibs-10.0"
