openSUSE Security Update : libXfont (openSUSE-2015-266)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

Description :

libXFont was updated to fix three vulnerabilities when parsing BDF
files (bnc#921978)

As libXfont is used by the X server to read font files, and an
unprivileged user with access to the X server can tell the X server to
read a given font file from a path of their choosing, these
vulnerabilities have the potential to allow unprivileged users to run
code with the privileges of the X server.

The following vulnerabilities were fixed :

- The BDF parser could allocate the a wrong buffer size,
leading to out of bound writes (CVE-2015-1802)

- The BDF parser could crash when trying to read an
invalid pointer (CVE-2015-1803)

- The BDF parser could read 32 bit metrics values into 16
bit integers, causing an out-of-bound memory access
though integer overflow (CVE-2015-1804)
