CWE-189  (opens in a new tab)

How to fix?

Upgrade libxfont to version 1.4.8 or higher.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). Multiple integer overflows in the (1) FontFileAddEntry and (2) lexAlias functions in X.Org libXfont before 1.4.8 and 1.4.9x before 1.4.99.901 might allow local users to gain privileges by adding a directory with a large fonts.dir or fonts.alias file to the font path, which triggers a heap-based buffer overflow, related to metadata.
