red hat
Calendar Grey November 16, 2010
Dist Redhat Esm H88
Critical alert regarding a crucial security patch for freetype impacting Red Hat Enterprise Linux, addressing significant buffer overflow vulnerabilities.
Updated freetype packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6

Solution

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. The freetype packages for Red Hat Enterprise Linux 4 provide both the FreeType 1 and FreeType 2 font engines. The freetype packages for Red Hat Enterprise Linux 5 and 6 provide only the FreeType 2 font engine.
A heap-based buffer overflow flaw was found in the way the FreeType font rendering engine processed certain TrueType GX fonts. If a user loaded a specially-crafted 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-2010-3855)
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.
