freetype security update (RHSA-2012-0467)

Original Release Date: May 3, 2012
Last Revised: July 7, 2015
Number: ASA-2012-202
Risk Level: Low
Advisory Version: 5.0
Advisory Status: Final

1. Overview:

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.

Multiple flaws were found in the way FreeType handled TrueType Font (TTF), Glyph Bitmap Distribution Format (BDF), Windows .fnt and .fon, and PostScript Type 1 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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2012-1134, CVE-2012-1136, CVE-2012-1142 and CVE-2012-1144 to these issues.

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 products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but customers should not modify the System Product operating system or application unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

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 affected Avaya products:

Vulnerability Mitigating Factors
CVE-2012-1126
CVE-2012-1127
CVE-2012-1130
CVE-2012-1131
CVE-2012-1132
CVE-2012-1134
CVE-2012-1136
CVE-2012-1137
CVE-2012-1139
CVE-2012-1140
CVE-2012-1141
CVE-2012-1142
CVE-2012-1143
CVE-2012-1144
These are a Low risk for all products because privileged account access would be required to install font files.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
