Background

A library for manipulating FlashPIX images.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/libfpx	< 1.3.1_p6	>= 1.3.1_p6	All supported architectures

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
