Description Adam Mariš 2017-11-02 09:56:47 UTC

Invalid json_populate_recordset() or jsonb_populate_recordset() calls crash
the server or disclose a few bytes of server memory. We have not ruled out
viability of attacks that arrange for presence of confidential information in
disclosed bytes, but they seem unlikely.

Vulnerable Versions: 9.3 - 10
