IBM DB2 9.1 before FP10, 9.5 before FP6a, and 9.7 before FP2 on Linux, UNIX, and Windows does not properly revoke the DBADM authority, which allows remote authenticated users to execute non-DDL statements by leveraging previous possession of this authority.

According to its version, the installation of IBM DB2 9.1 running on the remote host is prior to Fix Pack 10. It is, therefore, affected by one or more of the following issues :

  - It is possible to execute non-DDL statements even after     an user's DBADM authority has been revoked. (IC66811)

  - Multiple vulnerabilities in 'db2dasrrm' component could     allow arbitrary code execution. (IC71203)/(IC69986)

Versions of IBM DB2 9.1 earlier than Fix Pack 10 are potentially affected by multiple vulnerabilities :

  - Multiple buffer overflow vulnerabilities exist in the DB2 Administrative Service (DAS) which could lead to a denial-of-service, or the execution of arbitrary code. (IC69986, IC71203)
 - Users continue to have privilege to execute a non-DDL statement after their DBADM authority has been revoked. (IC66811)

Versions of IBM DB2 9.7 earlier than Fix Pack 2 are potentially affected by multiple vulnerabilities :

  -  If the database configuration parameter 'AUTO_REVAL' is set to 'IMMEDIATE', system granted privileges are note regenerated. (IC67008)
 - 'Monitor Administrative Views' available in the SYSIBMADM schema are publicly viewable. (IC67819)
 - A weakness in the SSL v3 / TLS protocol involving session renegotiation may allow an attacker to inject an arbitrary amount of plaintext into the beginning of the application protocol stream, which could facilitate man-in-the-middle attacks. (IC68055)
 - By sending a specially crafted packet to Tivoli Monitoring Agent (KUDDB2) listening on TCP port 6014, it may be possible to trigger a denial of service condition. (IC68762)

According to its version, the installation of IBM DB2 9.7 running on the remote host is affected by one or more of the following issues :

  - The 'MODIFIED SQL DATA' table function is not dropped     when a definer loses required privileges to maintain     the objects. (IC63548)

  - A privilege escalation vulnerability exists in the     DB2STST program (on Linux and Unix platforms only).     (IC65742)

  - A malicious user could use the DB2DART program to     overwrite files owned by the instance owner. (IC65762)

  - The scalar function REPEAT contains a buffer overflow     that a malicious user with a valid database connection     could manipulate, causing the DB2 server to trap.     (IC65935)

  - Special group and user enumeration operation on the DB2     server or DB2 Administrator Server (DAS) could trap     when running on Windows 2008. (IC66643)

  - It is possible to execute non-DDL statements even after     an user's DBADM authority has been revoked. (IC66815)

  - If the database configuration parameter 'AUTO_REVAL' is     set to 'IMMEDIATE', system granted privileges are not     regenerated. (IC67008)

  - 'Monitor Administrative Views' available in SYSIBMADM     schema are publicly viewable. (IC67819)

  - A weakness in the SSL v3 / TLS protocol involving     session renegotiation may allow an attacker to inject     an arbitrary amount of plaintext into the beginning of     the application protocol stream, which could facilitate     man-in-the-middle attacks. (IC68055)

  - By sending a specially crafted packet to the Tivoli     Monitoring Agent (KUDDB2), which listens on TCP port     6014 by default, it may be possible to trigger a denial     of service condition. (IC68762)
