Updated postgresql packages fix security vulnerabilities CVE-2019-10129: Memory disclosure in partition routing Prior to this release, a user running PostgreSQL 11 can read arbitrary bytes of server memory by executing a purpose-crafted INSERT statement to a partitioned table. CVE-2019-10130: Selectivity estimators bypass row security policies PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this release, a user able to execute SQL queries with permissions to read a given column could craft a leaky operator that could read whatever data had been sampled from that column. If this happened to include values from rows that the user is forbidden to see by a row security policy, the user could effectively bypass the policy. This is fixed by only allowing a non-leakproof operator to use this data if there are no relevant row security policies for the table.
