Multiple integer overflows were reported, one of which Peter Valchev
|
|
(Google Security) found to be leading to a heap-based buffer overflow
|
|
in the cairo_image_surface_create_from_png() function that processes
|
|
PNG images.

<impact type="normal">

<p>
|
|
A remote attacker could entice a user to view or process a specially
|
|
crafted PNG image file in an application linked against Cairo, possibly
|
|
leading to the execution of arbitrary code with the privileges of the
|
|
user running the application.

There is no known workaround at this time.

All Cairo users should upgrade to the latest version:

<code>
|

# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=x11-libs/cairo-1.4.12"</code>
