Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : firefox vulnerabilities (USN-1548-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

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)

Frederic 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 Gregoire 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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected firefox package.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.3
(CVSS2#E:F/RL:OF/RC:ND)
Public Exploit Available : true
