Ubuntu Security Notice USN-1157-3

firefox regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04
Summary:
Under certain circumstances, the updated translations could unintentionally
install firefox.
Software Description:
- firefox: Safe and easy web browser from Mozilla
Details:
USN-1157-1 fixed vulnerabilities in Firefox. Unfortunately, this update
produced the side effect of pulling in Firefox on some systems that did not
have it installed during a dist-upgrade due to changes in the Ubuntu
language packs. This update fixes the problem. We apologize for the
inconvenience.
Original advisory details:
Bob Clary, Kevin Brosnan, Gary Kwong, Jesse Ruderman, Christian Biesinger,
Bas Schouten, Igor Bukanov, Bill McCloskey, Olli Pettay, Daniel Veditz and
Marcia Knous discovered multiple memory vulnerabilities in the browser
rendering engine. An attacker could possibly execute arbitrary code with
the privileges of the user invoking Firefox. (CVE-2011-2374, CVE-2011-2375)
Martin Barbella discovered that under certain conditions, viewing a XUL
document while JavaScript was disabled caused deleted memory to be
accessed. An attacker could potentially use this to crash Firefox or
execute arbitrary code with the privileges of the user invoking Firefox.
(CVE-2011-2373)
Jordi Chancel discovered a vulnerability on multipart/x-mixed-replace
images due to memory corruption. An attacker could potentially use this to
crash Firefox or execute arbitrary code with the privileges of the user
invoking Firefox. (CVE-2011-2377)
Chris Rohlf and Yan Ivnitskiy discovered an integer overflow vulnerability
in JavaScript Arrays. An attacker could potentially use this to execute
arbitrary code with the privileges of the user invoking Firefox.
(CVE-2011-2371)
It was discovered that Firefox's WebGL textures did not honor same-origin
policy. If a user were tricked into viewing a malicious site, an attacker
could potentially view image data from a different site. (CVE-2011-2366)
Christoph Diehl discovered an out-of-bounds read vulnerability in WebGL
code. An attacker could potentially read data that other processes had
stored in the GPU. (CVE-2011-2367)
Christoph Diehl discovered an invalid write vulnerability in WebGL code. An
attacker could potentially use this to execute arbitrary code with the
privileges of the user invoking Firefox. (CVE-2011-2368)
It was discovered that an unauthorized site could trigger an installation
dialog for addons and themes. If a user were tricked into viewing a
malicious site, an attacker could possibly trick the user into installing a
malicious addon or theme. (CVE-2011-2370)
Mario Heiderich discovered a vulnerability in displaying decoded
HTML-encoded entities inside SVG elements. An attacker could utilize this
to perform cross-site scripting attacks. (CVE-2011-2369)
