Bug ID: 1203719
Summary: CVE-2015-1804 libXfont: out-of-bounds memory access in
bdfReadCharacters
Product: Security Response
Component: vulnerability
Keywords: Security
Severity: medium
Priority: medium
Assignee: security-response-team(a)redhat.com
Reporter: mprpic(a)redhat.com

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.
