The DRDA Services component in IBM DB2 9.1 before FP7 and 9.5 before FP4 allows remote attackers to cause a denial of service (memory corruption and application crash) via an IPv6 address in the correlation token in the APPID string, as demonstrated by an APPID string sent by the third-party DataDirect JDBC driver 3.7.32.

Security readout for executives and security teams

CVE-2009-1906 is a remote denial-of-service issue in IBM DB2 DRDA Services. Certain DB2 9.1 and 9.5 builds can crash when handling a problematic APPID string containing an IPv6 address. The known business impact is availability loss, not data theft. Exposure is most likely in legacy IBM DB2 9.1 or 9.5 environments running DRDA Services, especially where DB2 listeners are reachable by untrusted clients or older JDBC middleware. Treat this as a targeted legacy-system availability risk. It is not supported by active exploitation evidence in the bundle, but exposed old DB2 systems should be prioritized for upgrade or isolation. Mitigation focus: Upgrade DB2 9.1 to FP7 or later if still in use.; Upgrade DB2 9.5 to FP4 or later if still in use.; Check IBM APAR guidance for platform-specific fixes and prerequisites..
