| 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.
