+Subject: [PATCH 1/8] crypt: Fix validation of malformed BCrypt hashes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+PHP’s implementation of crypt_blowfish differs from the upstream Openwall
+version by adding a “PHP Hack”, which allows one to cut short the BCrypt salt
+by including a `$` character within the characters that represent the salt.
+
+Hashes that are affected by the “PHP Hack” may erroneously validate any
+password as valid when used with `password_verify` and when comparing the
+return value of `crypt()` against the input.
+
+The PHP Hack exists since the first version of PHP’s own crypt_blowfish
+implementation that was added in 1e820eca02dcf322b41fd2fe4ed2a6b8309f8ab5.
+
+No clear reason is given for the PHP Hack’s existence. This commit removes it,
+because BCrypt hashes containing a `$` character in their salt are not valid
+BCrypt hashes.
+

+Subject: [PATCH 3/8] Fix array overrun when appending slash to paths
+
+Fix it by extending the array sizes by one character. As the input is
+limited to the maximum path length, there will always be place to append
+the slash. As the php_check_specific_open_basedir() simply uses the
+strings to compare against each other, no new failures related to too
+long paths are introduced.
+We'll let the DOM and XML case handle a potentially too long path in the
+library code.
