Background ========== The AMD64 x86 emulation Qt library for AMD64 emulates the x86 (32-bit) Qt library on the AMD64 (64-bit) architecture. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 emul-linux-x86-qtlibs < 10.0 >= 10.0 Description =========== An integer overflow flaw has been found in the pixmap handling of Qt, making the AMD64 x86 emulation Qt library vulnerable as well. Impact ====== By enticing a user to open a specially crafted pixmap image in an application using the AMD64 x86 emulation Qt library, a remote attacker could cause an application crash or the remote execution of arbitrary code with the rights of the user running the application. Workaround ========== There is no known workaround at this time. Resolution ========== All AMD64 x86 emulation Qt library users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-qtlibs-10.0" References ========== [ 1 ] GLSA 200611-02 http://www.gentoo.org/security/en/glsa/glsa-200611-02.xml [ 2 ] CVE-2006-4811 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4811 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-06.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.
