red hat
Calendar Grey August 15, 2011
Dist Redhat Esm H88
A necessary security patch for freetype packages on Red Hat Enterprise Linux targeting a critical buffer overflow vulnerability.
Updated freetype packages that fix one security issue are now available for Red Hat Enterprise Linux 4

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259

Summary

FreeType is a free, high-quality, portable font engine that can open and manage font files. It also loads, hints, and renders individual glyphs efficiently. These packages provide both the FreeType 1 and FreeType 2 font engines.
A buffer overflow flaw was found in the way the FreeType library handled malformed font files compressed using UNIX compress. If a user loaded a specially-crafted compressed font file with an application linked against FreeType, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2011-2895)
Note: This issue only affects the FreeType 2 font engine.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. The X server must be restarted (log out, then log back in) for this update to take effect.
