Multiple security issues were found in PHP, a widely-used open source general purpose scripting language, which could result in denial of service or incorrect validation of BCrypt hashes.
Due to an uncaught integer overflow, `PDO::quote()` of PDO_SQLite may return an improperly quoted string. The exact details likely depend on the implementation of `sqlite3_snprintf()`, but with some versions it is possible to force the function to return a single apostrophe, if the function is called on user supplied input without any length restrictions in place.
Tim Düsterhus discovered that malformed BCrypt hashes that include a `$` within their salt part trigger a buffer overread and may erroneously validate any password as valid. (`Password_verify()` always return `true` with such inputs.)
1-byte array overrun when appending slash to paths during path resolution.
Jakob Ackermann discovered a Denial of Service vulnerability when parsing multipart request body: the request body parsing in PHP allows any unauthenticated attacker to consume a large amount of CPU time and trigger excessive logging.
For Debian 8 jessie, these problems have been fixed in version 5.6.40+dfsg-0+deb8u17.
We recommend that you upgrade your php5 packages.
