Several vulnerabilities have been discovered in Iceweasel, a web browser based on Firefox. The included XULRunner library provides rendering services for several other applications included in Debian.

  - CVE-2012-0455     Soroush Dalili discovered that a cross-site scripting     countermeasure related to JavaScript URLs could be     bypassed.

  - CVE-2012-0456     Atte Kettunen discovered an out of bounds read in the     SVG Filters, resulting in memory disclosure.

  - CVE-2012-0458     Mariusz Mlynski discovered that privileges could be     escalated through a JavaScript URL as the home page.

  - CVE-2012-0461     Bob Clary discovered memory corruption bugs, which may     lead to the execution of arbitrary code.

Soroush Dalili discovered that Firefox did not adequately protect against dropping JavaScript links onto a frame. A remote attacker could, through cross-site scripting (XSS), exploit this to modify the contents or steal confidential data. (CVE-2012-0455)

Atte Kettunen discovered a use-after-free vulnerability in Firefox's handling of SVG animations. An attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2012-0457)

Atte Kettunen discovered an out of bounds read vulnerability in Firefox's handling of SVG Filters. An attacker could potentially exploit this to make data from the user's memory accessible to the page content. (CVE-2012-0456)

Mike Brooks discovered that using carriage return line feed (CRLF) injection, one could introduce a new Content Security Policy (CSP) rule which allows for cross-site scripting (XSS) on sites with a separate header injection vulnerability. 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-2012-0451)

Mariusz Mlynski discovered that the Home button accepted JavaScript links to set the browser Home page. An attacker could use this vulnerability to get the script URL loaded in the privileged about:sessionrestore context. (CVE-2012-0458)

Daniel Glazman discovered that the Cascading Style Sheets (CSS) implementation is vulnerable to crashing due to modification of a keyframe followed by access to the cssText of the keyframe. If the user were tricked into opening a specially crafted web 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-2012-0459)

Matt Brubeck discovered that Firefox did not properly restrict access to the window.fullScreen object. If the user were tricked into opening a specially crafted web page, an attacker could potentially use this vulnerability to spoof the user interface. (CVE-2012-0460)

Bob Clary, Christian Holler, Jesse Ruderman, Michael Bebenita, David Anderson, Jeff Walden, Vincenzo Iozzo, and Willem Pinckaers 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-2012-0461, CVE-2012-0462, CVE-2012-0464).

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.

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2012-0387 advisory.

    firefox:

    [10.0.3-1.0.1.el6_2]
    - Add firefox-oracle-default-prefs.js and remove the corresponding Red Hat ones

    [10.0.3-1]
    - Update to 10.0.3 ESR

    xulrunner:

    [10.0.3-1.0.1.el6_2]
    - Replace xulrunner-redhat-default-prefs.js with
    - xulrunner-oracle-default-prefs.js

    [10.0.3-1]
    - Update to 10.0.3 ESR

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
