Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : firefox regression (USN-1548-2)

Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

USN-1548-1 fixed vulnerabilities in Firefox. The new package caused a
regression in Private Browsing which could leak sites visited to the
browser cache. This update fixes the problem.

Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary,
Andrew Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and
Daniel Holbert discovered memory safety issues affecting Firefox. If
the user were tricked into opening a specially crafted page, an
attacker could exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Firefox. (CVE-2012-1970, CVE-2012-1971)

Abhishek Arya discovered multiple use-after-free
vulnerabilities. If the user were tricked into opening a
specially crafted page, an attacker could exploit these to
cause a denial of service via application crash, or
potentially execute code with the privileges of the user
invoking Firefox. (CVE-2012-1972, CVE-2012-1973,
CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956,
CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,
CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

Mariusz Mlynsk discovered that it is possible to shadow the
location object using Object.defineProperty. This could
potentially result in a cross-site scripting (XSS) attack
against plugins. With cross-site scripting vulnerabilities,
if a user were tricked into viewing a specially crafted
page, a remote attacker could exploit this to modify the
contents or steal confidential data within the same domain.
(CVE-2012-1956)

Mariusz Mlynski discovered an escalation of privilege
vulnerability through about:newtab. This could possibly lead
to potentially code execution with the privileges of the
user invoking Firefox. (CVE-2012-3965)

Frédéric Hoguin discovered that bitmap format images with
a negative height could potentially result in memory
corruption. If the user were tricked into opening a
specially crafted image, an attacker could exploit this to
cause a denial of service via application crash, or
potentially execute code with the privileges of the user
invoking Firefox. (CVE-2012-3966)

It was discovered that Firefox's WebGL implementation was
vulnerable to multiple memory safety issues. If the user
were tricked into opening a specially crafted page, an
attacker could exploit these to cause a denial of service
via application crash, or potentially execute code with the
privileges of the user invoking Firefox. (CVE-2012-3967,
CVE-2012-3968)

Arthur Gerkis discovered multiple memory safety issues in
Firefox's Scalable Vector Graphics (SVG) implementation. If
the user were tricked into opening a specially crafted
image, an attacker could exploit these to cause a denial of
service via application crash, or potentially execute code
with the privileges of the user invoking Firefox.
(CVE-2012-3969, CVE-2012-3970)

Christoph Diehl discovered multiple memory safety issues in
the bundled Graphite 2 library. If the user were tricked
into opening a specially crafted page, an attacker could
exploit these to cause a denial of service via application
crash, or potentially execute code with the privileges of
the user invoking Firefox. (CVE-2012-3971)

Nicolas Grégoire discovered an out-of-bounds read in the
format-number feature of XSLT. This could potentially cause
inaccurate formatting of numbers and information leakage.
(CVE-2012-3972)

Mark Goodwin discovered that under certain circumstances,
Firefox's developer tools could allow remote debugging even
when disabled. (CVE-2012-3973)

It was discovered that when the DOMParser is used to parse
text/html data in a Firefox extension, linked resources
within this HTML data will be loaded. If the data being
parsed in the extension is untrusted, it could lead to
information leakage and potentially be combined with other
attacks to become exploitable. (CVE-2012-3975)

Mark Poticha discovered that under certain circumstances
incorrect SSL certificate information can be displayed on
the addressbar, showing the SSL data for a previous site
while another has been loaded. This could potentially be
used for phishing attacks. (CVE-2012-3976)

It was discovered that, in some instances, certain security
checks in the location object could be bypassed. This could
allow for the loading of restricted content and can
potentially be combined with other issues to become
exploitable. (CVE-2012-3978)

Colby Russell discovered that eval in the web console can
execute injected code with chrome privileges, leading to the
running of malicious code in a privileged context. If the
user were tricked into opening a specially crafted page, an
attacker could exploit this to cause a denial of service via
application crash, or potentially execute code with the
privileges of the user invoking Firefox. (CVE-2012-3980).

Solution :

Update the affected firefox package.
