gThumb is an image viewer and browser for GNOME.
A heap-based buffer overflow in gThumb’s _cairo_image_surface_create_from_jpeg() function, located in extensions/cairo_io/cairo-image-surface-jpeg.c was discovered.
A remote attacker could entice a user to open a specially crafted image file using gThumb, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All gThumb users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/gthumb-3.10.0"
