  script_tag(name:"affected", value:"IBM Db2 versions 9.5 before Fix Pack 6a.");

  script_tag(name:"insight", value:"Multiple flaws are due to:

  - An error in 'Install' component, which enforces an unintended limit on
    password length, which makes it easier for attackers to obtain access via
    a brute-force attack.

  - A buffer overflow in the 'Administration Server' component, which allows an
    attacker to cause a denial of service via unspecified vectors.

  - An error in 'DRDA Services' component, which allows remote authenticated
    users to cause a denial of service.

  - The 'Engine Utilities' component uses world-writable permissions for the
   'sqllib/cfg/db2sprf' file, which allows local users to gain privileges by
    modifying this file.

  - A memory leak in the 'Relational Data Services' component, when the
    connection concentrator is enabled.

  - The 'Query Compiler, Rewrite, Optimizer' component, allows remote
    authenticated users to cause a denial of service (CPU consumption).

  - 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.

  - The 'Net Search Extender' (NSE) implementation in the Text Search component
    does not properly handle an alphanumeric Fuzzy search.

  - The audit facility in the 'Security' component uses instance-level audit
    settings to capture connection (aka CONNECT and AUTHENTICATION) events in
    certain circumstances in which database-level audit settings were intended.");
