  - the imap_open functions which allows to run arbitrary shell commands via mailbox parameter.

  - a Heap Buffer Overflow (READ: 4) in phar_parse_pharfile.

  - ext/standard/var_unserializer.c allows attackers to cause a denial of service (application crash)
  via an unserialize call for the com, dotnet, or variant class.

  - because com and com_safearray_proxy return NULL in com_properties_get in ext/com_dotnet/com_handlers.c,
  as demonstrated by a serialize call on COM('WScript.Shell').");
