Ubuntu Security Notice 2052-1 - Ben Turner, Bobby Holley, Jesse Ruderman, Christian Holler and Christoph Diehl discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. Myk Melez discovered that the doorhanger notification for web app installation could persist between page navigations. An attacker could potentially exploit this to conduct clickjacking attacks. Various other issues were also addressed.

==========================================================================

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

- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Firefox could be made to crash or run programs as your login if it
opened a malicious website.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Ben Turner, Bobby Holley, Jesse Ruderman, Christian Holler and Christoph
Diehl discovered multiple memory safety issues in Firefox. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Firefox. (CVE-2013-5609, CVE-2013-5610)

Myk Melez discovered that the doorhanger notification for web app
installation could persist between page navigations. An attacker could
potentially exploit this to conduct clickjacking attacks. (CVE-2013-5611)

Masato Kinugawa discovered that pages with missing character set encoding
information can inherit character encodings across navigations from
another domain. An attacker could potentially exploit this to conduct
cross-site scripting attacks. (CVE-2013-5612)

Daniel Veditz discovered that a sandboxed iframe could use an object
element to bypass its own restrictions. (CVE-2013-5614)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
event listeners. An attacker could potentially exploit this to cause a
denial of service via application crash, or execute arbitrary code with
the privileges of the user invoking Firefox. (CVE-2013-5616)

A use-after-free was discovered in the table editing interface. An
attacker could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2013-5618)

Dan Gohman discovered that binary search algorithms in Spidermonkey
used arithmetic prone to overflow in several places. However, this
is issue not believed to be exploitable. (CVE-2013-5619)

Tyson Smith and Jesse Schwartzentruber discovered a crash when inserting
an ordered list in to a document using script. An attacker could
potentially exploit this to execute arbitrary code with the privileges
of the user invoking Firefox. (CVE-2013-6671)

Vincent Lefevre discovered that web content could access clipboard data
under certain circumstances, resulting in information disclosure.
(CVE-2013-6672)

Sijie Xia discovered that trust settings for built-in EV root certificates
were ignored under certain circumstances, removing the ability for a user
to manually untrust certificates from specific authorities.
(CVE-2013-6673)

Tyson Smith, Jesse Schwartzentruber and Atte Kettunen discovered a
use-after-free in functions for synthetic mouse movement handling. An
attacker could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code with the privileges of the
user invoking Firefox. (CVE-2013-5613)

Eric Faust discovered that GetElementIC typed array stubs can be generated
outside observed typesets. An attacker could possibly exploit this to
cause undefined behaviour with a potential security impact.
(CVE-2013-5615)

Michal Zalewski discovered several issues with JPEG image handling. An
attacker could potentially exploit these to obtain sensitive information.
(CVE-2013-6629, CVE-2013-6630)

Update instructions:

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

Ubuntu 13.10:
firefox 26.0+build2-0ubuntu0.13.10.2

Ubuntu 13.04:
firefox 26.0+build2-0ubuntu0.13.04.2

Ubuntu 12.10:
firefox 26.0+build2-0ubuntu0.12.10.2

Ubuntu 12.04 LTS:

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