Stack-based buffer overflow in the gfig_read_parameter_gimp_rgb function in plug-ins/gfig/gfig-style.c in the GFIG plugin in GIMP 2.6.11 allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long Foreground field in a plugin configuration file.  NOTE: it may be uncommon to obtain a GIMP plugin configuration file from an untrusted source that is separate from the distribution of the plugin itself. NOTE: some of these details are obtained from third party information.
