PHP 4.3.8 Released, Fixing Remote Security Hole

Posted by timothy on from the constant-progress dept.

christian klink writes "While it was already reported on Slashdot, that PHP5 was released, it was not mentioned that the PHP developers have also announced the release of PHP 4.3.8 which is supposed to fix a major remote security hole in nearly all PHP installations. Additionally this new version adds a workaround for another Internet Explorer bug. The bugs were found by security specialist Stefan Esser of e-matters who is also a member of the PHP developers."

  1. not exploitable everywhere? by brlewis · · Score: 2, Interesting
    It sounds like this hole cannot be exploited unless you've enabled certain extensions. I'm actually no longer using a host where PHP is turned on...never used PHP itself. Now I'm on Jetty with a UML host. Just curious about the hole...is my assessment correct?
    One of such places is f.e. within the fileupload code, but is only triggerable on Apache 2 servers that are vulnerable to CAN-2004-0493, another one is only reachable if variables_order was changed to have the "E" in the end, a third one is within session extension which is activated by default but the vulnerability can not be triggered if the session functionality is not used. A fourth place is within the implementation of the register_globals functionality. Although this is deactivated by default since PHP 4.2 it is activated on nearly all servers that have to ensure compatibility with older scripts. Other places might exist in not default activated or 3rd party extensions.
