Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.

The ip_push_pending_frames function in Linux 2.4.x and 2.6.x before 2.6.16 increments the IP ID field when sending a RST after receiving unsolicited TCP SYN-ACK packets, which allows remote attackers to conduct an Idle Scan (nmap -sI) attack, which bypasses intended protections against such attacks.


How to mitigate CVE-2006-1242

Install update from vendor's repository.
