Technical details
A classic buffer overflow (CWE-120) in IBM Guardium Data Protection's Sniffer component allows a remote attacker to send malicious network packets that overflow a fixed-size buffer, leading to arbitrary code execution. The vulnerability requires no authentication but has high complexity (network timing/conditions); successful exploitation results in complete system compromise with confidentiality, integrity, and availability impact.
