Problem summary
**************************************************************** USERS AFFECTED: Users that open a queue with MQOO_SAVE_ALL_CONTEXT (including Message Broker) and perform MQGET of a message containing multiple RFHs with duplicate folders shared between them. for example: first rfh2: <folder1><prop1>value</prop1></folder1> <folder2><prop2>value</prop2></folder2> second rfh2: <folder1><prop3>value</prop3></folder1> <folder3><prop4>value</prop4></folder3> In this case, there are two instances of 'folder1' which need to be merged. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: The problem was caused by a miscalculation during the parsing of the RFH2 folders that caused invalid access to memory.
Problem conclusion
The problem is fixed by ensuring that the folders can be merged correctly. A correction to the calculation logic was necessary to prevent memory access outside of the message data. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.11 -------- -------------------- Windows 7.0.1.11 AIX 7.0.1.11 HP-UX (PA-RISC) 7.0.1.11 HP-UX (Itanium) 7.0.1.11 Solaris (SPARC) 7.0.1.11 Solaris (x86-64) 7.0.1.11 iSeries 7.0.1.11 Linux (x86) 7.0.1.11 Linux (x86-64) 7.0.1.11 Linux (zSeries) 7.0.1.11 Linux (Power) 7.0.1.11 v7.1 Platform Fix Pack 7.1.0.4 -------- -------------------- Windows 7.1.0.4 AIX 7.1.0.4 HP-UX (Itanium) 7.1.0.4 Solaris (SPARC) 7.1.0.4 Solaris (x86-64) 7.1.0.4 iSeries 7.1.0.4 Linux (x86) 7.1.0.4 Linux (x86-64) 7.1.0.4 Linux (zSeries) 7.1.0.4 Linux (Power) 7.1.0.4 Platform v7.5 -------- -------------------- Multiplatforms 7.5.0.2 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
