CVE-2002-2438

CVE-2002-2438 describes a vulnerability in the Linux TCP stack that allowed firewalls to be bypassed. Specifically, SYN packets containing additional flags (e.g., RST) were not properly discarded after firewalling, enabling attackers to circumvent security policies. This high-severity flaw (CVSS 7.5) has a network attack vector and low attack complexity, potentially leading to a denial of service. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this older vulnerability.
