CVE-2018-1426: IBM GSKit (IBM DB2 for Linux, UNIX and Windows 9.7, 10.1, 10.5, and 11.1) duplicates the PRNG state across...

Security readout for executives and security teams

This flaw can cause IBM DB2’s cryptographic library to reuse randomness after process forks. In practical terms, some DB2 deployments could create duplicate session identifiers or duplicate key material, weakening confidentiality and integrity protections. The CVSS rating is high, but exploitation is listed as high complexity. Exposure is limited to IBM DB2 for Linux, UNIX and Windows versions 9.7, 10.1, 10.5, and 11.1 using affected GSKit behavior. Internet-facing or broadly reachable DB2 services deserve higher priority, especially where encrypted sessions protect sensitive data. Treat this as a high-priority cryptographic weakness for affected DB2 estates, especially where DB2 is reachable over networks or protects regulated data. It is not currently supported by KEV evidence of exploitation, so prioritize with exposure and data sensitivity rather than emergency assumptions. Mitigation focus: Review IBM advisory swg22013756 for the vendor-prescribed fix for each DB2 version.; Apply the relevant IBM DB2 or GSKit update where available.; Restrict network access to DB2 services while remediation is planned..
