I think this was fixed in 8.0.2... > CVE-2005-0244 PostgreSQL 8.0.0 and earlier allows local users to bypass the > EXECUTE permission check for functions by using the CREATE AGGREGATE > command.

The CVE says it only affected pre-8.0 releases and I'm inclined to believe it. > CVE-2005-0246 The intagg contrib module for PostgreSQL 8.0.0 and earlier > allows attackers to cause a denial of service (crash) via crafted arrays. Contrib modules are only an issue if you install them. If you don't need them, don't install them. Don't know if this was fixed but honestly I expect it was, the Postgres folks don't just sit around on their hands when CVE's come out. > CVE-2005-0247 Multiple buffer overflows in gram.y for PostgreSQL 8.0.1 and > earlier may allow attackers to execute arbitrary code via (1) a large number > of variables in a SQL statement being handled by the read_sql_construct > function, (2) a large number of INTO variables in a SELECT statement being > handled by the make_select_stmt function, (3) alarge number of arbitrary > variables in a SELECT statement being handled > by the make_select_stmt function, and (4) a large number of INTO variables > in a FETCH statement being handled by the make_fetch_stmt function, a > different set of vulnerabilities than CVE-2005-0245.

This appears to have been fixed in 8.0.3. It looks like these were all fixed rather quickly after they were discovered and brought to the attention of the PostgreSQL team. http://www.gsa.gov/networx -> Networx Hosting Center -> NHC User Instructions, Executive Summary. No software is without bugs. It would be foolish to assume that you can deploy a system once and never have to update it for newly discovered security vulnerabilities. If you'd like a comparison to a product they may be allowing elsewhere you might consider looking at Oracle's track record for fixing security issues. It's rather... poor. There have been a number of articles to this affect on bugtraq recently, you shouldn't have too much trouble finding good examples. Enjoy, Stephen
