Background ========== Cairo is a 2D vector graphics library with cross-device output support. The AMD64 x86 emulation GTK+ library packages Cairo libraries for 32bit x86 emulation on AMD64. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 emul-linux-x86-gtklibs < 20071214 >= 20071214 ------------------------------------------------------------------- # Package 1 only applies to AMD64 users. Description =========== The Cairo versions used by the AMD64 x86 emulation GTK+ libraries were vulnerable to integer overflow vulnerabilities (GLSA 200712-04). 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 AMD64 x86 emulation GTK+ library users should upgrade to the latest version: # emerge --sync # emerge -a -1 -v ">=app-emulation/emul-linux-x86-gtklibs-20071214" References ========== [ 1 ] GLSA 200712-04 http://www.gentoo.org/security/en/glsa/glsa-200712-04.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200712-24.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
