(CVE-2014-6159) Document information More support for: DB2 for Linux, UNIX and Windows Software version: 9.7, 9.8, 10.1, 10.5 Operating system(s): AIX, HP-UX, Linux, Solaris, Windows Software edition: Advanced Enterprise Server, Advanced Workgroup Server, Enterprise Server, Express, Express-C, Personal, Workgroup Server Reference #: 1688051 Modified date: 2014-11-05 Security Bulletin Summary IBM DB2 contains a vulnerability in which an ALTER TABLE statement may cause the DB2 server to terminate abnormally when AUTO_REVAL is set to IMMEDIATE . This could result in a DB2 server crash; if so, the server would need to be restarted. Vulnerability Details CVE ID: CVE-2014-6159 DESCRIPTION: IBM DB2 contains a disruption of service vulnerability. A remote, authenticated DB2 user could exploit this vulnerability when DB2 is configured with immediate auto revalidation (i.e. AUTO_REVAL configuration parameter is set to IMMEDIATE). The user would need valid security credentials to connect to the database and would need to execute specially crafted ALTER table statements (that require control privileges on the target table). Note: the AUTO_REVAL configuration parameter is set to DEFERRED by default.
