Synopsis ========
Multiple integer overflows were discovered in Cairo, possibly leading to the execution of arbitrary code.
Background ==========
Cairo is a 2D vector graphics library with cross-device output support.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/cairo < 1.4.12 >= 1.4.12
Description ===========
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 ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Cairo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/cairo-1.4.12"
References ==========
