Summary
IBM Guardium Data Protection 12.0 and 12.1 are vulnerable to a heap-based buffer overflow in the S-TAP TrafficTap TDS login reassembly functionality. An unauthenticated remote attacker can send crafted TDS login fragments exceeding the fixed-size reassembly buffer, potentially resulting in denial of service or arbitrary code execution.
Risk Assessment
A remote attack could cause system downtime or takeover, posing a serious threat to availability and security.
Recommendation
Apply patches from IBM for Guardium Data Protection 12.0 and 12.1, and restrict network access to TDS services.
