Libgdiplus: Arbitrary code execution

Background

Libgdiplus is the Mono library that provide a GDI+ comptible API on non-Windows operating systems.

Description

An integer overflow flaw has been discovered in Libgdiplus.

Impact

A remote attacker could entice a user to open a specially-crafted TIFF/JPEG/BMP file, potentially resulting in arbitrary code execution.

Workaround

There is no known workaround at this time.

Resolution

All Libgdiplus users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-dotnet/libgdiplus-2.6.7-r1"

Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying some of these packages.

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 12, 2010. It is likely that your system is already no longer affected by this issue.
