Synopsis

- An error exists in the ASN.1 decoder when handling zero length items that can lead to application crashes. (CVE-2012-0441) - Multiple memory corruption errors exist. (CVE-2012-1937, CVE-2012-1038) - Two heap-based buffer overflows and one heap-based use-after-free error exist and are potentially exploitable. (CVE-2012-1940, CVE-2012-1941, CVE-2012-1947) - Two arbitrary DLL load issues exist related to the application update and update service functionality.

(CVE-2012-1946)

Solution
