Debian 9: DLA-2749-1 Moderate: Buffer Overflow in Gthumb Image Viewer

An issue has been found in gthumb, an image viewer and browser.
A heap-based buffer overflow in _cairo_image_surface_create_from_jpeg()
in extensions/cairo_io/cairo-image-surface-jpeg.c allows attackers to
cause a crash and potentially execute arbitrary code via a crafted JPEG
file.


For Debian 9 stretch, this problem has been fixed in version
3:3.4.4.1-5+deb9u2.

We recommend that you upgrade your gthumb packages.
