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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2010-3855 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow
networking and security best practices by implementing
firewalls, ACLs, physical security or other appropriate
access restrictions. Though Avaya believes such
restrictions should always be in place; risk to Avaya's
product and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as a product
update is available or the recommended action is applied.
Further restrictions as deemed necessary based on the
customer's security policies may be required during this
interim period.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for the listed affected Avaya products:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2010-3855 |
Avaya has rated this a Low for all products as it would require non-standard direct user interaction, such as loading a specially crafted font file, to exploit. |
