Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Lukasz Wojtow has reported a vulnerability in MySQL, potentially allowing malicious people to compromise a vulnerable system.

The problem is that the "mysql_real_connect()" function doesn't properly verify the length of IP addresses returned by a reverse DNS lookup of a hostname. This could potentially be exploited to cause a buffer overflow and execute arbitrary code.

Successful exploitation requires that the attacker is able to return a malicious DNS reply when a MySQL user connects to a server.

This has been reported in MySQL 4.0.20 and prior.

It has been reported that this can't be exploited on the Linux and OpenBSD platforms.
