Updated libxfont packages fix security vulnerabilities :
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
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).
The bdf parser reads a count for the number of properties defined in a
font from the font file, and allocates arrays with entries for each
property based on that count. It never checked to see if that count
was negative, or large enough to overflow when multiplied by the size
of the structures being allocated, and could thus allocate the wrong
buffer size, leading to out of bounds writes (CVE-2015-1802).
If the bdf parser failed to parse the data for the bitmap for any
character, it would proceed with an invalid pointer to the bitmap data
and later crash when trying to read the bitmap from that pointer
The bdf parser read metrics values as 32-bit integers, but stored them
into 16-bit integers. Overflows could occur in various operations
leading to out-of-bounds memory access (CVE-2015-1804).
