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  - It is possible to execute non-DDL statements even after     an user's DBADM authority has been revoked.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

According to its version, the installation of IBM DB2 9.7 running on the remote host is prior Fix Pack 3. It is, therefore, affected by one or more of the following issues :

  - When privileges on a database object are revoked from     PUBLIC, the dependent functions are not marked INVALID.
    As a result, users with execute privilege on the     function are still able to call it successfully.
    (IC68015)

  - If a compound SQL (compiled) statement has been issued     by a user that is properly authorized, this is cached in     the dynamic SQL cache.  Once cached, this same query can     be executed by any user if that user has the proper     authority. (IC70406)

  - Multiple vulnerabilities in 'db2dasrrm' component could     allow arbitrary code execution. (IC70539 / IC72029)

According to its version, the installation of IBM DB2 9.5 running on the remote host is prior to 9.5 Fix Pack 6. It is, therefore, affected by one or more of the following issues :

  - The Install component on Linux, UNIX, and Windows     enforces an unintended limit on password length, which     makes it easier for attackers to obtain access via a     brute-force attack. (IC62856)     
  - The Security component logs AUDIT events by using a     USERID and an AUTHID value corresponding to the instance     owner, instead of a USERID and an AUTHID value     corresponding to the logged-in user account, which makes     it easier for remote, authenticated users to execute     Audit administration commands without discovery.
    (IC65184)

  - A privilege escalation vulnerability exists in the     DB2STST program (on Linux and Unix platforms only).     (IC65703)

  - A malicious user could use the DB2DART program to     overwrite files owned by the instance owner. (IC65756)

  - 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.     (IC65933)

  - The Net Search Extender implementation in the Text     Search component does not properly handle an     alphanumeric Fuzzy search, which could allow a remote,     authenticated user to consume memory or even hang     the system via the 'db2ext.textSearch' function.
    (IC66613)

  - Special group and user enumeration operation on the DB2     server or DB2 Administrator Server (DAS) could trap     when running on Windows 2008. (IC66642)

  - 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. (IC68054)

  - A memory leak in the Relational Data Services component,     when the connection concentrator is enabled, allows     remote, authenticated users to cause a denial of service     (heap memory consumption) by using a different code page     than the database server. (IC68182)

  - An unspecified remote buffer overflow vulnerability exists     in the DB2 administrative server. (IC70538)

  - The 'MODIFIED SQL DATA' table function is not dropped     when a definer loses required privileges to maintain     the objects. (IZ46774)

  - The DRDA Services component allows a remote,     authenticated user to cause the database server to     ABEND by using the client CLI on Linux, UNIX, or     Windows for executing a prepared statement with a large     number of parameter markers. (IZ56428)

  - The 'Query Compiler, Rewrite, Optimizer' component     allows remote, authenticated users to cause a denial of     service (CPU consumption) via a crafted query involving     certain UNION ALL views, leading to an indefinitely     large amount of compilation time. (IZ58417)

  - The Engine Utilities component uses world-writable     permissions for the 'sqllib/cfg/db2sprf' file, which     could allow a local user to gain privileges by modifying     this file. (IZ68463)

  - The audit facility in the Security component uses     instance-level audit settings to capture CONNECT and     AUTHENTICATION events in certain circumstances in which     database-level audit settings were intended, which might     make it easier for remote attackers to connect without     discovery. (JR34218)

  - A memory leak in the Relational Data Services component     allows remote, authenticated users to cause a denial of     service (heap memory consumption) by executing a user-     defined function (UDF) or stored procedure while using a     different code page than the database server. (LI75022)

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 3 are potentially affected by multiple vulnerabilities :

 - When privileges on a database object are revoked from PUBLIC, the dependent functions are not marked INVALID.  As a result, users with execute privilege on the function are still able to call it successfully. (IC68015)
 - If a compound SQL (compiled) statement has been issued by a user that is properly authorized, this is cached in the dynamic SQL cache.  Once cached, this same query can be executed by an user if that user has the proper authority. (IC70406)
 - Multiple buffer overflow vulnerabilities exist in the DB2 Administrative Server (DAS). (IC70539, IC72029)
