Background ========== X.Org is an implementation of the X Window System. The X.Org X11 library provides the X11 protocol library files. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-libs/libX11 < 1.0.3-r2 >= 1.0.3-r2 Description =========== Multiple integer overflows have been reported in the XGetPixel() function of the X.Org X11 library. Impact ====== By enticing a user to open a specially crafted image, an attacker could cause a Denial of Service or an integer overflow, potentially resulting in the execution of arbitrary code with root privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All X.Org X11 library users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=x11-libs/libX11-1.0.3-r2" References ========== [ 1 ] CVE-2007-1667 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1667 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200705-06.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.
