The Phar extension for PHP does not properly handle crafted tar files, leading to a heap-based buffer overflow. PHP applications processing tar files could crash or, potentially, execute arbitrary code.
In addition, this update addresses a regression which caused a crash when accessing a global object that is returned as $this from __get.
