Benoit Jacob, Jesse Ruderman, Christian Holler, Bill McCloskey, Brian Smith, Gary Kwong, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey discovered memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. Mario Gomes discovered that the address bar may be incorrectly updated. Drag-and-drop events in the address bar may cause the address of the previous site to be displayed while a new page is loaded. An attacker could exploit this to conduct phishing attacks. Various other issues were also addressed.

Gary Kwong, Christoph Diehl, Chris Jones, Brad Lassey, and Kyle Huey discovered
memory safety issues affecting Firefox. If the user were tricked into opening a
specially crafted page, an attacker could possibly exploit these to cause a
denial of service via application crash, or potentially execute code with the
privileges of the user invoking Firefox. (CVE-2012-1948, CVE-2012-1949)

Mario Gomes discovered that the address bar may be incorrectly updated.
Drag-and-drop events in the address bar may cause the address of the previous
site to be displayed while a new page is loaded. An attacker could exploit this
to conduct phishing attacks. (CVE-2012-1950)

Abhishek Arya discovered four memory safety issues affecting Firefox. If the
user were tricked into opening a specially crafted page, an attacker could
possibly exploit these to cause a denial of service via application crash, or

Mariusz Mlynski discovered that the address bar may be incorrectly updated.
Calls to history.forward and history.back could be used to navigate to a site
while the address bar still displayed the previous site. A remote attacker
could exploit this to conduct phishing attacks. (CVE-2012-1955)

Mario Heiderich discovered that HTML <embed> tags were not filtered out of the
HTML <description> of RSS feeds. A remote attacker could exploit this to
conduct cross-site scripting (XSS) attacks via javascript execution in the HTML
feed view. (CVE-2012-1957)

Arthur Gerkis discovered a use-after-free vulnerability. If the user were
tricked into opening a specially crafted page, an attacker could possibly

execute code with the privileges of the user invoking Firefox. (CVE-2012-1958)

Bobby Holley discovered that same-compartment security wrappers (SCSW) could be
bypassed to allow XBL access. If the user were tricked into opening a specially
crafted page, an attacker could possibly exploit this to execute code with the
privileges of the user invoking Firefox. (CVE-2012-1959)

Tony Payne discovered an out-of-bounds memory read in Mozilla's color
management library (QCMS). If the user were tricked into opening a specially

denial of service via application crash. (CVE-2012-1960)

Fr=E9d=E9ric Buclin discovered that the X-Frame-Options header was ignored when its
value was specified multiple times. An attacker could exploit this to conduct
clickjacking attacks. (CVE-2012-1961)

Update instructions:

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

Ubuntu 12.04 LTS:
ubufox 2.1.1-0ubuntu0.12.04.1
xul-ext-ubufox 2.1.1-0ubuntu0.12.04.1

Ubuntu 11.10:
ubufox 2.1.1-0ubuntu0.11.10.1
xul-ext-ubufox 2.1.1-0ubuntu0.11.10.1

Ubuntu 11.04:
ubufox 2.1.1-0ubuntu0.11.04.1
xul-ext-ubufox 2.1.1-0ubuntu0.11.04.1

Ubuntu 10.04 LTS:
ubufox 2.1.1-0ubuntu0.10.04.1
xul-ext-ubufox 2.1.1-0ubuntu0.10.04.1

When upgrading, users should be aware of the following:

- In Ubuntu 11.04, unity-2d users may lose the ability to view drop-down menus,
context menus, and perform drag-and-drop operations in Firefox. This is a known
issue being tracked in https://launchpad.net/bugs/1020198 and may be fixed in a
later update.

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