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.
