Description:
mercenary has discovered a vulnerability in PHP, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the handling of the named pipe part of the "server" parameter passed to the "mysql_connect()" PHP function in the "HANDLE create_named_pipe()" function in "libmysql.c". This can be exploited to cause a stack-based buffer overflow via a PHP script calling "mysql_connect()" where the "server" parameter can be controlled by the attacker.
NOTE: Exploit code is publicly available.
The vulnerability has been confirmed in version 4.4.1 for Windows. Versions 4.3.10 and 4.4.0 for Windows are reportedly also affected. Other versions may also be affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.
Solution:
Update to version 4.4.3.
