LI72519: POTENTIAL MEMORY CORRUPTION AND/OR INSTANCE CRASH DURING DB2 UDB AUTHENTICATION

 

APAR status

  • Closed as program error.

Error description

  • This APAR deals with the following related issues:
    .
    1) During authentication, DB2 UDB saves the authentication
    information (e.g. groups) to a list located in memory. It has
    been discovered that on several occasions, for example during
    memory allocation failures, the list is handled improperly.
    This may result in potential memory corruption and/or instance
    crashes in DB2 UDB authentication routines. The exact external
    symptoms of the problem are not yet known. The purpose of this
    APAR is to improve the handling of the in-memory list.
    .
    2) This APAR also improves the diagnostic data gathered
    during problems in DB2 authentication routines. This will
    simplify future investigations of such problems.
