Original advisory details:

 It was discovered that if a user chose to export their Firefox Sync key
 the 'Firefox Recovery Key.html' file is saved with incorrect permissions,
 making the file contents potentially readable by other users.
 (CVE-2012-0450)

 Nicolas Gregoire and Aki Helin discovered that when processing a malformed
 embedded XSLT stylesheet, Firefox can crash due to memory corruption. If
 the user were tricked into opening a specially crafted page, an attacker
 could exploit this to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking Firefox.
 (CVE-2012-0449)

 It was discovered that memory corruption could occur during the decoding of
 Ogg Vorbis files. If the user were tricked into opening a specially crafted
 file, an attacker could exploit this to cause a denial of service via
 application crash, or potentially execute code with the privileges of the
 user invoking Firefox. (CVE-2012-0444)

 Tim Abraldes discovered that when encoding certain images types the
 resulting data was always a fixed size. There is the possibility of
 sensitive data from uninitialized memory being appended to these images.
 (CVE-2012-0447)

 It was discovered that Firefox did not properly perform XPConnect security
 checks. An attacker could exploit this to conduct cross-site scripting
 (XSS) attacks through web pages and Firefox extensions. With cross-site
 scripting vulnerabilities, if a user were tricked into viewing a specially
 crafted page, a remote attacker could exploit this to modify the contents,
 or steal confidential data, within the same domain. (CVE-2012-0446)

 It was discovered that Firefox did not properly handle node removal in the
 DOM. If the user were tricked into opening a specially crafted page, an
 attacker could exploit this to cause a denial of service via application
 crash, or potentially execute code with the privileges of the user invoking
 Firefox. (CVE-2011-3659)

 Alex Dvorov discovered that Firefox did not properly handle sub-frames in
 form submissions. An attacker could exploit this to conduct phishing
 attacks using HTML5 frames. (CVE-2012-0445)

 Ben Hawkes, Christian Holler, Honza Bombas, Jason Orendorff, Jesse
 Ruderman, Jan Odvarko, Peter Van Der Beken, Bob Clary, and Bill McCloskey
 discovered memory safety issues affecting Firefox. If the user were tricked
 into opening a specially crafted page, an attacker could exploit these to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Firefox. (CVE-2012-0442,
 CVE-2012-0443)");
