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-2009-0352, CVE-2009-0353)

A flaw was discovered in the JavaScript engine. An attacker could bypass the
same-origin policy in Firefox by utilizing a chrome XBL method and execute
arbitrary JavaScript within the context of another website. (CVE-2009-0354)

A flaw was discovered in the browser engine when restoring closed tabs. If a
user were tricked into restoring a tab to a malicious website with form input
controls, an attacker could steal local files on the user’s system.
(CVE-2009-0355)

Wladimir Palant discovered that Firefox did not restrict access to cookies in
HTTP response headers. If a user were tricked into opening a malicious web
page, a remote attacker could view sensitive information. (CVE-2009-0357)

Paul Nel discovered that Firefox did not honor certain Cache-Control HTTP
directives. A local attacker could exploit this to view private data in
improperly cached pages of another user. (CVE-2009-0358)
