(CVE-2010-1208, CVE-2010-1209, CVE-2010-1211, CVE-2010-1212,<br>CVE-2010-1214, CVE-2010-1215, CVE-2010-2752, CVE-2010-2753)<br>A memory corruption flaw was found in the way Firefox decoded certain PNG<br>images. An attacker could create a specially-crafted PNG image that, when<br>opened, could cause Firefox to crash or, potentially, execute arbitrary<br>code with the privileges of the user running Firefox. (CVE-2010-1205)<br>Several same-origin policy bypass flaws were found in Firefox. An attacker<br>could create a malicious web page that, when viewed by a victim, could<br>steal private data from a different website the victim has loaded with<br>Firefox.
