Users able to update statistics for tables without appropriate privileges | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
Users are able to incorrectly update statistics columns in SYSSTAT.TABLES for tables upon which they do not have appropriate privileges. Thus, a malicious user may be able to introduce query performance degradations by modifying table statistics via this view. Normally, in order to update the statistics for a table via this view, you must have CONTROL or explicit DATAACCESS privilege on the table. This APAR fix addresses this problem. | |
