Description:   Several vulnerabilities were reported in libXfont. A remote or local user can cause arbitrary code to be executed on the target user's system.

A local user can create specially crafted 'fonts.dir' and 'fonts.alias' files to trigger a heap overflow [CVE-2014-0209].

A remote font server can return a specially crafted XFS protocol message to trigger a memory overflow [CVE-2014-0210].

Certain functions do not properly check for buffer overflows [CVE-2014-0211]. The fs_get_reply(), fs_alloc_glyphs(), and fs_read_extent_info() functions are affected.
