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

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

- Ubuntu 11.04

Summary:

Multiple Firefox vulnerabilities have been fixed

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Aral Yaman discovered a vulnerability in the WebGL engine. An attacker
could potentially use this to crash Firefox or execute arbitrary code with
the privileges of the user invoking Firefox. (CVE-2011-2989)

Vivekanand Bolajwar discovered a vulnerability in the JavaScript engine. An
attacker could potentially use this to crash Firefox or execute arbitrary
code with the privileges of the user invoking Firefox. (CVE-2011-2991)

Bert Hubert and Theo Snelleman discovered a vulnerability in the Ogg
reader. An attacker could potentially use this to crash Firefox or execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2011-2991)

Robert Kaiser, Jesse Ruderman, Gary Kwong, Christoph Diehl, Martijn
Wargers, Travis Emmitt, Bob Clary, and Jonathan Watt discovered multiple
memory vulnerabilities in the browser rendering engine. An attacker could
use these to possibly execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2011-2985)

Rafael Gieschke discovered that unsigned JavaScript could call into a
script inside a signed JAR. This could allow an attacker to execute
arbitrary code with the identity and permissions of the signed JAR.
(CVE-2011-2993)

Michael Jordon discovered that an overly long shader program could cause a
buffer overrun. An attacker could potentially use this to crash Firefox or
execute arbitrary code with the privileges of the user invoking Firefox.
(CVE-2011-2988)

Michael Jordon discovered a heap overflow in the ANGLE library used in
Firefox's WebGL implementation. An attacker could potentially use this to
crash Firefox or execute arbitrary code with the privileges of the user
invoking Firefox. (CVE-2011-2987)

It was discovered that an SVG text manipulation routine contained a
dangling pointer vulnerability. An attacker could potentially use this to
crash Firefox or execute arbitrary code with the privileges of the user
invoking Firefox. (CVE-2011-0084)

Mike Cardwell discovered that Content Security Policy violation reports
failed to strip out proxy authorization credentials from the list of
request headers. This could allow a malicious website to capture proxy
authorization credentials. Daniel Veditz discovered that redirecting to a
website with Content Security Policy resulted in the incorrect resolution
of hosts in the constructed policy. This could allow a malicious website to
circumvent the Content Security Policy of another website. (CVE-2011-2990)

Update instructions:

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

Ubuntu 11.04:
firefox 6.0+build1+nobinonly-0ubuntu0.11.04.1

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