FreeType in CoreGraphics in Apple iOS before 5.0.1 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted font in a document.

The remote Solaris system is missing necessary patches to address security updates :

  - FreeType in CoreGraphics in Apple iOS before 5.0.1     allows remote attackers to execute arbitrary code or     cause a denial of service (memory corruption) via a     crafted font in a document. (CVE-2011-3439)

This update of freetype2 fixes multiple security flaws that could allow attackers to cause a denial of service or to execute arbitrary code via specially crafted fonts (CVE-2011-3256, CVE-2011-3439).

FreeType allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted font.
(CVE-2011-3439, bnc#730124)

Multiple input validation flaws were found in the way FreeType processed CID-keyed fonts. If a specially crafted font file was loaded by an application linked against FreeType, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

From Red Hat Security Advisory 2011:1455 :

Updated freetype packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.
