CVE-2014-0209

Ilja van Sprundel discovered that libXfont incorrectly handled font metadata file parsing. A local attacker could use this issue to cause libXfont to crash, or possibly execute arbitrary code in order to gain privileges (CVE-2014-0209).

Ilja van Sprundel discovered that libXfont incorrectly handled X Font Server replies. A malicious font server could return specially-crafted data that could cause libXfont to crash, or possibly execute arbitrary code (CVE-2014-0210, CVE-2014-0211).

These are all security issues fixed in the libXfont-devel-1.5.2-1.1 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)

Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata.
