libfpx: Denial of service

Background

A library for manipulating FlashPIX images.

Description

A double free vulnerability has been discovered in the Free_All_Memory function in jpeg/dectile.c.

Impact

A remote attacker could entice a user to open a specially crafted FPX image using an application linked against libfpx, possibly resulting in a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All libfpx users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/libfpx-1.3.1_p6"

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