WILD POINTER REQUEST->AGT_RUNTIME_OBJ IN SQLQG_SIGNAL_HANDLER LEADS TO DATABASE CRASH
|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
sqlqg_signal_handler is called when errors are detected in db2
edu agent. sqlqg_signal_handler is responsible to dump the sqqg
(federation) runtime objects before the Db2 edu exit. In this
function it references a structure pointer and try to get the
data member of that structure. The pointer has been validated by
checking if it is' NULL' before actually using it. But the
memory that the pointer points to has been freed, it is a code
bug that this pointer has not been set to 'NULL'. |
