The PHP Team has announced that PHP 5.1.2 has been released with a few feature enhancements and bug fixes.

Three security issues fixed in this version are:

1. HTTP Response Splitting has been addressed in ext/session and in the header() function. Header() can no longer be used to send multiple response headers in a single call.
2. Format string vulnerability in ext/mysqli.
3. Possible cross-site scripting problems in certain error conditions.
