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

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

- 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:

Multiple memory safety issues were discovered in 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-2013-0801, CVE-2013-1669)

Cody Crews discovered that some constructors could be used to bypass
restrictions enforced by their Chrome Object Wrapper (COW). An attacker
could exploit this to conduct cross-site scripting (XSS) attacks.
(CVE-2013-1670)

It was discovered that the file input element could expose the full local
path under certain conditions. An attacker could potentially exploit this
to steal sensitive information. (CVE-2013-1671)

A use-after-free was discovered when resizing video content whilst it is
playing. An attacker could potentially exploit this to execute code with
the privileges of the user invoking Firefox. (CVE-2013-1674)

It was discovered that some DOMSVGZoomEvent functions could be used
without being properly initialized, which could lead to information
leakage. (CVE-2013-1675)

Abhishek Arya discovered multiple memory safety issues in 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-2013-1676, CVE-2013-1677, CVE-2013-1678,
CVE-2013-1679, CVE-2013-1680, CVE-2013-1681)

Update instructions:

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

Ubuntu 13.04:
  firefox                         21.0+build2-0ubuntu0.13.04.2

Ubuntu 12.10:
  firefox                         21.0+build2-0ubuntu0.12.10.2

Ubuntu 12.04 LTS:
  firefox                         21.0+build2-0ubuntu0.12.04.3

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