Details

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, CVE-2008-5501, CVE-2008-5502)

It was discovered that Firefox did not properly handle persistent cookie data.
If a user were tricked into opening a malicious website, an attacker could
write persistent data in the user’s browser and track the user across browsing
sessions. (CVE-2008-5505)

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)
