Having a Big weird Problem with IPB and PHP 4.4.5-dev
i upgraded my php version to the latest version 4.4.5-dev and i'm facing a strange problem with IPB
check this error please
IPB WARNING  preg_match() [function.preg-match]: Compilation failed: repeated subpattern is too long at offset 29167 (Line: 184 of /sources/classes/class_session.php)
i searched google for such a thing and i found nothin , the board was good and working under the php version 4.4.3 and when i upgraded this error happened
so any explaination or solution here ?!
the problem is the php 4.4.4 version is vuln. specially this serious vuln. of symlink() function to bypass openbase dir and read files and the only update is by upgrading the php version
" A vulnerability has been identified in PHP, which could be exploited by local attackers to bypass security restrictions. This flaw is due to a race condition between the time that "open_basedir" access controls for a symbolic link are verified and the time the requested file is accessed by certain functions, which could be exploited by malicious users to gain unauthorized access to restricted files via a PHP script containing "symlink()", "mkdir()", "unlink()", and "fopen()" calls.
