CVE-2003-0467 describes an unknown vulnerability in the ip_nat_sack_adjust function of Netfilter in Linux kernels 2.4.20 and some 2.5.x versions. This flaw, present when NAT FTP or IRC modules are enabled or loaded, allows remote attackers to trigger a denial of service (system crash) in NAT-enabled systems, possibly due to an integer signedness error. With a CVSS score of 5.0, it is considered a medium severity issue, requiring no authentication and having low attack complexity, but only impacting availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or media coverage, though it has garnered significant community discussion on platforms like GitHub.
