Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of IBM MQ on Unix or Linux Platforms affected: IBM iSeries, Linux on Power, Linux on x86-64, Linux on zSeries, AIX **************************************************************** PROBLEM DESCRIPTION: A logic error was identified within an MQ diagnostic function (xfdDumpProcDirCB), called when generating a failure data capture (FDC) file. If this routine were to receive an unexpected error code from an operating system "stat" call, the error handling could attempt to dereference an uninitialized variable.
Problem conclusion
The xfdDumpProcDirCB function has been corrected to avoid accessing the uninitialized variable in the event that "stat" returns an unexpected error code. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.3 LTS 9.3.0.20 v9.4 LTS 9.3.3 The latest available maintenance can be obtained from 'IBM MQ Recommended Fixes' https://www.ibm.com/support/pages/recommended-fixes-ibm-mq If the maintenance level is not yet available information on its planned availability can be found in 'IBM MQ Planned Maintenance Release Dates' https://ibm.biz/mqplannedmaintenance ---------------------------------------------------------------
