| Description: | Summary:
The remote host is missing an update for the 'mozilla'
package(s) announced via the referenced advisory.
Vulnerability Insight:
Security issues were identified and fixed in mozilla firefox and
thunderbird:
Mozilla developers identified and fixed several memory safety
bugs in the browser engine used in Firefox and other Mozilla-based
products. Some of these bugs showed evidence of memory corruption
under certain circumstances, and we presume that with enough effort
at least some of these could be exploited to run arbitrary code
(CVE-2012-1949, CVE-2012-1948).
Security researcher Mario Gomes andresearch firm Code Audit Labs
reported a mechanism to short-circuit page loads through drag and drop
to the addressbar by canceling the page load. This causes the address
of the previously site entered to be displayed in the addressbar
instead of the currently loaded page. This could lead to potential
phishing attacks on users (CVE-2012-1950).
Google security researcher Abhishek Arya used the Address Sanitizer
tool to uncover four issues: two use-after-free problems, one out of
bounds read bug, and a bad cast. The first use-after-free problem is
caused when an array of nsSMILTimeValueSpec objects is destroyed but
attempts are made to call into objects in this array later. The second
use-after-free problem is in nsDocument::AdoptNode when it adopts into
an empty document and then adopts into another document, emptying the
first one. The heap buffer overflow is in ElementAnimations when data
is read off of end of an array and then pointers are dereferenced. The
bad cast happens when nsTableFrame::InsertFrames is called with
frames in aFrameList that are a mix of row group frames and column
group frames. AppendFrames is not able to handle this mix. All four of
these issues are potentially exploitable (CVE-2012-1951, CVE-2012-1954,
CVE-2012-1953, CVE-2012-1952).
Security researcher Mariusz Mlynski reported an issue with spoofing
of the location property. In this issue, calls to history.forward
and history.back are used to navigate to a site while displaying the
previous site in the addressbar but changing the baseURI to the newer
site. This can be used for phishing by allowing the user input form
or other data on the newer, attacking, site while appearing to be on
the older, displayed site (CVE-2012-1955).
Mozilla security researcher moz_bug_r_a4 reported a cross-site
scripting (XSS) attack through the context menu using a data: URL. In
this issue, context menu functionality (View Image, Show only this
frame, and View background image) are disallowed in a javascript:
URL but allowed in a data: URL, allowing for XSS. This can lead to
