Ubuntu Security Notice 1401-1 - It was discovered that a flaw in the Mozilla SVG implementation could result in an out-of-bounds memory access if SVG elements were removed during a DOMAttrModified event handler. 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. Atte Kettunen discovered a use-after-free vulnerability in the Gecko Rendering Engine's handling of SVG animations. An attacker could potentially exploit this to execute arbitrary code with the privileges of the user invoking the Xulrunner based application. Atte Kettunen discovered an out of bounds read vulnerability in the Gecko Rendering Engine's handling of SVG Filters. An attacker could potentially exploit this to make data from the user's memory accessible to the page content. Various other issues were also addressed.

xulrunner-1.9.2 vulnerabilities
============================================================================

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

- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Firefox.

Software Description:
- xulrunner-1.9.2: Mozilla Gecko runtime environment

Details:

It was discovered that a flaw in the Mozilla SVG implementation could
result in an out-of-bounds memory access if SVG elements were removed
during a DOMAttrModified event handler. 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. (CVE-2011-3658)

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

Atte Kettunen discovered an out of bounds read vulnerability in the Gecko
Rendering Engine'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)

Soroush Dalili discovered that the Gecko Rendering Engine 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 of the frame or steal confidential data. (CVE-2012-0455)

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)

Bob Clary, 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-2012-0464)

Update instructions:

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

Ubuntu 10.10:
xulrunner-1.9.2 1.9.2.28+build1+nobinonly-0ubuntu0.10.10.1

Ubuntu 10.04 LTS:
xulrunner-1.9.2 1.9.2.28+build1+nobinonly-0ubuntu0.10.04.1

After a standard system update you need to restart any application based on
Xulrunner such as Yelp or Conkeror to make all the necessary changes.
