The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service (out-of-bounds memory access) and possibly execute arbitrary code via a crafted BDF font file.

CVE-2015-1802 libXfont vulnerabilities
Title: libXfont vulnerabilities
Summary: libXfont could be made to crash or run programs as an administrator
if it opened a specially crafted bdf font file.
Ilja van Sprundel, Alan Coopersmith, and William Robinet discovered that
libXfont incorrectly handled malformed bdf fonts. A local attacker could
use this issue to cause libXfont to crash, or possibly execute arbitrary
code in order to gain privileges.
Instructions: After a standard system update you need to reboot your computer to make
all the necessary changes.

CVE-2015-1804 [HIGH] CWE-704 libXfont: out-of-bounds memory access in bdfReadCharacters
libXfont: out-of-bounds memory access in bdfReadCharacters
The bdfReadCharacters function in bitmap/bdfread.c in X.Org libXfont before 1.4.9 and 1.5.x before 1.5.1 does not properly perform type conversion for metrics values, which allows remote authenticated users to cause a denial of service (out-of-bounds memory access) and possibly execute arbitrary code via a crafted BDF font file.
An integer truncation flaw was discovered in the way libXfont processed certain Glyph Bitmap Distribution Format (BDF) fonts. A malicious, local user could use this flaw to crash the X.Org server or, potentially, execute arbitrary code with the privileges of the X.Org server.

CVE-2015-1804 [HIGH] CVE-2015-1804 libXfont: out-of-bounds memory access in bdfReadCharacters
CVE-2015-1804 libXfont: out-of-bounds memory access in bdfReadCharacters
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.
A local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server.
