3. Description:
The libXfont package provides the X.Org libXfont runtime library. X.Org is
an open source implementation of the X Window System.
An integer overflow flaw was found 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-2015-1802)
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)
A NULL pointer dereference 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.
(CVE-2015-1803)
All libXfont users are advised to upgrade to this updated package, which
contains backported patches to correct these issues.
4. Solution:
Before applying this update, make sure all previously released errata
