Background ========== A library for manipulating FlashPIX images. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/libfpx < 1.3.1_p6 >= 1.3.1_p6 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.
