Description filip ambroz 2020-02-15 10:04:50 UTC
from URL:
The ALTER ... DEPENDS ON EXTENSION sub-commands do not perform authorization checks, which can allow an unprivileged user to drop any function, procedure, materialized view, index, or trigger under certain conditions. This attack is possible if an administrator has installed an extension and an unprivileged user can CREATE, or an extension owner either executes DROP EXTENSION predictably or can be convinced to execute DROP EXTENSION. The PostgreSQL project thanks Tom Lane for reporting this problem.

Versions Affected: 9.6 - 12

Solution: upgrade postrgresql packages

@ maintainer(s): Please explain why you don't want to stabilize =dev-db/postgresql-9.4.26 and =dev-db/postgresql-9.5.21 because previous 9.4.x and 9.5.x is also affected.

Sorry for the delayed response.

The reason I didn't initially include them is because neither 9.4 nor 9.5 is  affected as noted in comment #1, which is a copy of https://www.postgresql.org/about/news/2011/

But, at this point, they're now old enough to be stabilized,
