PHP 5.1.2. Release Announcement
The PHP development team is proud to announce the release of PHP 5.1.2.
This release combines small feature enhancements with a fair number of
bug fixes and addresses three security issues. All PHP 5 users are encouraged to
upgrade to this release.
The security issues resolved include the following:
- 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.
- Format string vulnerability in ext/mysqli.
- Possible cross-site scripting problems in certain error conditions.
The feature enhancements include the following notables:
- Hash extension was added to core and is now enabled by default. This
extension provides support for most common hashing algorithms without
reliance on 3rd party libraries.
- XMLWriter was added and enabled by default.
- New OCI8 extension that includes numerous fixes.
- PNG compression support added to the GD extension.
- Added --enable-gcov configure option to enable C-level code coverage.

imap, pdo, gd, mysqli, mcrypt and soap extensions.
