Date:27 февраля 2008 г.
Subject:Mozilla Foundation Security Advisory 2008-07

Mozilla Foundation Security Advisory 2008-07

Title: Possible information disclosure in BMP decoder
Impact: Moderate
Announced: February 19, 2008
Reporter: Gynvael Coldwind // Vexillium
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox
 SeaMonkey 1.1.8

Security researcher Gynvael Coldwind of Vexillium (crediting help from udevd and porneL) demonstrated that BMP images could be used to reveal small chunks of uninitialized memory that might contain sensitive data from other pages or other programs, and that this data could be extracted from the image using methods associated with the <canvas> feature.

Because this flaw also affected products from other vendors disclosure was delayed until they could release a fix.

Disable JavaScript until a version containing these fixes can be installed.
