IBM Guardium Data Protection: Buffer overflow in Sniffer component
Summary
IBM Guardium Data Protection versions 12.0, 12.1 and 12.2 contain a buffer overflow (CWE-119) in the Sniffer component. A remote attacker may be able to execute arbitrary code on the affected system. The CVE record provided lists CVSS 8.8 with low attack complexity, while the IBM bulletin lists 7.5 with high attack complexity and low privileges required; the score should be verified on NVD.
Affected
- IBM Guardium Data Protection 12.0
- IBM Guardium Data Protection 12.1
- IBM Guardium Data Protection 12.2
- Component: Sniffer
Fixed in
- IBM recommends applying the latest IBM Guardium Data Protection Sniffer patch for all affected versions.

- Exact fixed level per version: Unknown (see IBM bulletin 7291674).
Workaround
- None listed by IBM.
Exploitation
- CISA SSVC: exploitation none, not automatable, total technical impact.
- No public exploit known (VulDB).
- Not known to be exploited in the wild.
Our recommendation
- Apply the latest IBM Guardium Data Protection Sniffer patch on all systems running 12.0, 12.1 or 12.2.
- Verify the installed fixed level against IBM bulletin 7291674.
- Restrict network access to Guardium collectors and aggregators and keep them out of the internet.
- Prioritise the other Sniffer flaws in the same bulletin, since one patch cycle covers them.
