CVE-2006-1242
Linux Kernel < 2.6.16 - Idle Scan Attack via IP ID Increment in ip_push_pending_frames
Title source: llmDescription
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.
