    description NVIDIA Unix security team reports : The GLX indirect rendering support supplied on NVIDIA products is subject to the recently disclosed X.Org vulnerabilities (CVE-2014-8093, CVE-2014-8098) as well as internally identified vulnerabilities (CVE-2014-8298). Depending on how it is configured, the X server typically runs with raised privileges, and listens for GLX indirect rendering protocol requests from a local socket and potentially a TCP/IP port. The vulnerabilities could be exploited in a way that causes the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution.

    description Andreas Cord-Landwehr reported an issue where the X.Org Xserver would often crash with an arithmetic exception when maximizing application windows. This issue (CVE-2015-3418) is a regression which got introduced by fixing CVE-2014-8092. The above referenced version of xorg-server in Debian squeeze-lts fixes this regression in the following way : The length checking code validates PutImage height and byte width by making sure that byte-width >= INT32_MAX / height. If height is zero, this generates a divide by zero exception. Allow zero height requests explicitly, bypassing the INT32_MAX check (in dix/dispatch.c). NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description Alan Coopersmith reports : Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way the X server code base handles requests from X clients, and has worked with X.Org's security team to analyze, confirm, and fix these issues. The vulnerabilities could be exploited to cause the X server to access uninitialized memory or overwrite arbitrary memory in the X server process. This can cause a denial of service (e.g., an X server segmentation fault), or could be exploited to achieve arbitrary code execution. The GLX extension to the X Window System allows an X client to send X protocol to the X server, to request that the X server perform OpenGL rendering on behalf of the X client. This is known as 'GLX indirect rendering', as opposed to 'GLX direct rendering' where the X client submits OpenGL rendering commands directly to the GPU, bypassing the X server and avoiding the X server code for GLX protocol handling. Most GLX indirect rendering implementations share some common ancestry, dating back to 'Sample Implementation' code from Silicon Graphics, Inc (SGI), which SGI originally commercially licensed to other Unix workstation and graphics vendors, and later released as open source, so those vulnerabilities may affect other licensees of SGI's code base beyond those running code from the X.Org Foundation or the XFree86 Project.

Olivier Fourdan from Red Hat has discovered a protocol handling issue in the way the X server code base handles the XkbSetGeometry request, where the server trusts the client to send valid string lengths. A malicious client with string lengths exceeding the request length can cause the server to copy adjacent memory data into the XKB structs. This data is then available to the client via the XkbGetGeometry request. This can lead to information disclosure issues, as well as possibly a denial of service if a similar request can cause the server to crash (CVE-2015-0255).

(CVE-2014-8092, CVE-2014-8093, CVE-2014-8098) It was found that the X.Org server did not properly handle SUN-DES-1 (Secure RPC) authentication credentials. A malicious, unauthenticated client could use this flaw to crash the X.Org server by submitting a specially crafted authentication request. (CVE-2014-8091) Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server, or leak memory contents to the client. (CVE-2014-8097) Multiple out-of-bounds access flaws were found in the way the X.Org server calculated memory requirements for certain requests. A malicious, authenticated client could use either of these flaws to crash the X.Org server. (CVE-2014-8095, CVE-2014-8096, CVE-2014-8099, CVE-2014-8100, CVE-2014-8101, CVE-2014-8102) All xorg-x11-server users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
