A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as: If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only affects Firefox on Windows when run in non-standard configurations (such as using runas). Other operating systems are unaffected.
