Description Josh Bressers 2005-03-30 14:52:21 UTC 
PostgreSQL 7.2.1 and 7.2.2 allows local users to delete transaction log
(pg_clog) data and cause a denial of service (data loss) via the VACUUM command.

Comment 1 Josh Bressers 2005-03-30 14:53:05 UTC 
Tom,

Can you take a look at this issue and let me know if we're vulnerable.  I've not
verified it one way of the other.
Comment 2 Tom Lane 2005-03-30 18:19:31 UTC 
AFAIK Red Hat has never shipped Postgres 7.2.anything --- we went from 7.1.* to
7.3.*.  Certainly 2.1AS is still using 7.1.3.  (No, this issue doesn't apply to
PG 7.1.*.)
