MGASA-2021-0121 - Updated postgresql packages fix security vulnerabilities

Publication date: 12 Mar 2021
Type: security
Affected Mageia releases: 7, 8
CVE: CVE-2021-3393,

A user having an UPDATE privilege on a partitioned table but lacking the SELECT
privilege on some column may be able to acquire denied-column values from an
error message (CVE-2021-3393).

A user having a SELECT privilege on an individual column can craft a special
query that returns all columns of the table. Additionally, a stored view that
uses column-level privileges will have incomplete column-usage bitmaps. In
installations that depend on column-level permissions for security, it is
recommended to execute CREATE OR REPLACE on all user-defined views to force
them to be re-parsed (CVE-2021-20229).

PostgreSQL 11 was only affected by CVE-2021-3393 and both PostgreSQL 11 and 13
were affected by CVE-2021-20229.  PostgreSQL 9.6 was updated to fix bugs.
