Description Martin Prpič 2015-10-13 03:18:45 EDT

An uninitialized pointer use flaw was found in the phar_make_dirstream() function of PHP's Phar extension. A specially crafted phar file in the ZIP format with a directory entry with a file name "/ZIP" could cause a PHP application function to crash.
