Gentoo: GLSA-200712-04: Cairo: User-assisted execution of arbitrary code
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200712-04 https://security.gentoo.org/
Severity: Normal Title: Cairo: User-assisted execution of arbitrary code Date: December 09, 2007 Bugs: #200350 ID: 200712-04
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
========== 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 ========= [ 1 ] CVE-2007-5503 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5503
