3. Description:
Mozilla Firefox is an open source web browser. XULRunner provides the XUL
Runtime environment for Mozilla Firefox.
A web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2012-1970, 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)
A web page containing a malicious Scalable Vector Graphics (SVG) image file
could cause Firefox to crash or, potentially, execute arbitrary code with
the privileges of the user running Firefox. (CVE-2012-3969, CVE-2012-3970)
Two flaws were found in the way Firefox rendered certain images using
WebGL. A web page containing malicious content could cause Firefox to crash
or, under certain conditions, possibly execute arbitrary code with the
privileges of the user running Firefox. (CVE-2012-3967, CVE-2012-3968)
A flaw was found in the way Firefox decoded embedded bitmap images in Icon
Format (ICO) files. A web page containing a malicious ICO file could cause
Firefox to crash or, under certain conditions, possibly execute arbitrary
code with the privileges of the user running Firefox. (CVE-2012-3966)
A flaw was found in the way the "eval" command was handled by the Firefox
Web Console. Running "eval" in the Web Console while viewing a web page
containing malicious content could possibly cause Firefox to execute
arbitrary code with the privileges of the user running Firefox.
(CVE-2012-3980)
An out-of-bounds memory read flaw was found in the way Firefox used the
format-number feature of XSLT (Extensible Stylesheet Language
Transformations). A web page containing malicious content could possibly
cause an information leak, or cause Firefox to crash. (CVE-2012-3972)
It was found that the SSL certificate information for a previously visited
site could be displayed in the address bar while the main window displayed
a new page. This could lead to phishing attacks as attackers could use this
flaw to trick users into believing they are viewing a trusted site.
(CVE-2012-3976)
A flaw was found in the location object implementation in Firefox.
Malicious content could use this flaw to possibly allow restricted content
to be loaded. (CVE-2012-3978)
For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.7 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.
Red Hat would like to thank the Mozilla project for reporting these issues.
