GIMP is the GNU Image Manipulation Program.
Marsu discovered that the "set_color_table()" function in the SUNRAS plugin is vulnerable to a stack-based buffer overflow.
An attacker could entice a user to open a specially crafted .RAS file, possibly leading to the execution of arbitrary code with the privileges of the user running GIMP.
There is no known workaround at this time.
All GIMP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/gimp-2.2.14"
