CVE-2013-1996

X.org libFS 1.0.4 and earlier allows X servers to trigger allocation of insufficient memory and a buffer overflow via vectors related to an unexpected sign extension in the FSOpenServer function.

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 (CVE-2013-1981, CVE-2013-1982, CVE-2013-1983, CVE-2013-1984, CVE-2013-1985, CVE-2013-1986, CVE-2013-1987, CVE-2013-1988, CVE-2013-1989, CVE-2013-1990, CVE-2013-1991, CVE-2013-1992, CVE-2013-1993, CVE-2013-1994, CVE-2013-1995, CVE-2013-1996, CVE-2013-1997, CVE-2013-1998, CVE-2013-1999, CVE-2013-2000, CVE-2013-2001, CVE-2013-2002, CVE-2013-2003, CVE-2013-2004, CVE-2013-2005, CVE-2013-2062, CVE-2013-2063, CVE-2013-2064, CVE-2013-2066).

An out-of-bounds access flaw was found in Mesa. If an application using Mesa exposed the Mesa API to untrusted inputs (Mozilla Firefox does this), an attacker could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application (CVE-2013-1872).

These are all security issues fixed in the libFS-devel-1.0.7-1.8 package on the GA media of openSUSE Tumbleweed.

xorg-x11-libs was patched to fix the following security issues:

* Integer overflow of allocations in font metadata file parsing.
  (CVE-2014-0209)
* libxfont not validating length fields when parsing xfs protocol
  replies. (CVE-2014-0210)
* Integer overflows causing miscalculating memory needs for xfs
  replies. (CVE-2014-0211)
