  - The (1) GetDatabase and (2) _XimParseStringFile     functions in X.org libX11 1.5.99.901 (1.6 RC1) and     earlier do not restrict the recursion depth when     processing directives to include files, which allows X     servers to cause a denial of service (stack consumption)     via a crafted file. (CVE-2013-2004)

  - X.org libXt 1.1.3 and earlier does not check the return     value of the XGetWindowProperty function, which allows X     servers to trigger use of an uninitialized pointer and     memory corruption via vectors related to the (1)     ReqCleanup, (2) HandleSelectionEvents, (3) ReqTimedOut,     (4) HandleNormal, and (5) HandleSelectionReplies     functions. (CVE-2013-2005)

This update of xorg-x11-libs fixes several integer and buffer overflow issues. (bnc#815451, bnc#821663)

Ilja van Sprundel discovered multiple security issues in various X.org libraries and components. An attacker could use these issues to cause applications to crash, resulting in a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

freedesktop.org reports :

Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues.

Most of these issues stem from the client libraries trusting the server to send correct protocol data, and not verifying that the values will not overflow or cause other damage. Most of the time X clients & servers are run by the same user, with the server more privileged from the clients, so this is not a problem, but there are scenarios in which a privileged client can be connected to an unprivileged server, for instance, connecting a setuid X client (such as a screen lock program) to a virtual X server (such as Xvfb or Xephyr) which the user has modified to return invalid data, potentially allowing the user to escalate their privileges.

The vulnerabilities include :

Integer overflows calculating memory needs for replies.

Sign extension issues calculating memory needs for replies.

Buffer overflows due to not validating length or offset values in replies.

Integer overflows parsing user-specified files.

Unbounded recursion parsing user-specified files.

Memory corruption due to unchecked return values.

Update to latest git to fix the following CVEs: CVE-2013-1996

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Ilja van Sprundel of IOActive discovered several security issues in multiple components of the X.org graphics stack and the related libraries: Various integer overflows, sign handling errors in integer conversions, buffer overflows, memory corruption and missing input sanitising may lead to privilege escalation or denial of service.
