Vulnerability Note VU#964549
Mozilla WOFF decoder integer overflow
An integer overflow in the Mozilla Web Open Fonts Format (WOFF) decoder may allow a remote attacker to execute code on an affected system.
The Web Open Fonts Format (WOFF) is a simple compressed file format for fonts. Mozilla introduced support for WOFF in the 1.9.2 branch of the base software, which is used by Firefox versions 3.6 and later.
An integer overflow error exists in the way the WOFF decoder handles the size of tables specified in the font file. This error could result in a buffer overflow vulnerability on a subsequent memory allocation. A remote attacker who is able to supply a malicious WOFF file could exploit this vulnerability.
A remote, unauthenticated attack may be able to execute arbitrary code with the privileges of the victim user.
Disable downloading of remote fonts
