Insight
Several flaws were discovered in the browser engine. These problems could allow an attacker to crash the browser and possibly execute arbitrary code with user privileges. (CVE-2008-5500) Boris Zbarsky discovered that the same-origin check in Firefox could be bypassed by utilizing XBL-bindings. An attacker could exploit this to read data from other domains. (CVE-2008-5503) Several problems were discovered in the JavaScript engine. An attacker could exploit feed preview vulnerabilities to execute scripts from page content with chrome privileges. (CVE-2008-5504) Marius Schilder discovered that Firefox did not properly handle redirects to an outside domain when an XMLHttpRequest was made to a same-origin resource. It's possible that sensitive information could be revealed in the XMLHttpRequest response. (CVE-2008-5506) Chris Evans discovered that Firefox did not properly protect a user's data when accessing a same-domain Javascript URL that is redirected to an unparsable Javascript off-site resource. If a user were tricked into opening a malicious website, an attacker may be able to steal a limited amount of private data. (CVE-2008-5507) Chip Salzenberg, Justin Schuh, Tom Cross, and Peter William discovered Firefox did not properly parse URLs when processing certain control characters. (CVE-2008-5508) Kojima Hajime discovered that Firefox did not properly handle an escaped null character. An attacker may be able to exploit this flaw to bypass script sanitization. (CVE-2008-5510) Several flaws were discovered in the Javascript engine. If a user were tricked into opening a malicious website, an attacker could exploit this to execute arbitrary Javascript code within the context of another website or with chrome privileges. (CVE-2008-5511, CVE-2008-5512) Flaws were discovered in the session-restore feature of Firefox. If a user were tricked into opening a malicious website, an attacker could exploit this to perform cross-site scripting attacks or execute arbitrary Javascript code with chrome privileges. (CVE-2008-5513)
