Ubuntu Security Notice USN-1306-1

firefox vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

Several security issues were fixed in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Alexandre Poirot, Chris Blizzard, Kyle Huey, Scoobidiver, Christian Holler,
David Baron, Gary Kwong, Jim Blandy, Bob Clary, Jesse Ruderman, Marcia
Knous, and Rober Longson discovered several memory safety issues which
could possibly be exploited to crash Firefox or execute arbitrary code as
the user that invoked Firefox. (CVE-2011-3660)

Aki Helin discovered a crash in the YARR regular expression library that
could be triggered by javascript in web content. (CVE-2011-3661)

It was discovered that a flaw in the Mozilla SVG implementation could
result in an out-of-bounds memory access if SVG elements were removed
during a DOMAttrModified event handler. An attacker could potentially
exploit this vulnerability to crash Firefox. (CVE-2011-3658)

Mario Heiderich discovered it was possible to use SVG animation accessKey
events to detect key strokes even when JavaScript was disabled. A malicious
web page could potentially exploit this to trick a user into interacting
with a prompt thinking it came from the browser in a context where the user
believed scripting was disabled. (CVE-2011-3663)

It was discovered that it was possible to crash Firefox when scaling an OGG
<video> element to extreme sizes. (CVE-2011-3665)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
firefox 9.0.1+build1-0ubuntu0.11.10.2

Ubuntu 11.04:
firefox 9.0.1+build1-0ubuntu0.11.04.1

After a standard system update you need to restart Firefox to make
all the necessary changes.
