#25109 [NEW]: pgsql causes segmentation fault
From: cunha17 at uol dot com dot br
Operating system: Redhat Linux 9.0 - Kernel 2.4.21
PHP version: 4.3.3RC3
PHP Bug Type: PostgreSQL related
Bug description: pgsql causes segmentation fault
Description:
------------
I found out that pgsql functions cause segmentation fault if the
connection user has no read access on pg_ system tables.
I'm using John Lim's ADOdb class to access a PostgreSQL 7.2.4 database.
This problem has nothing to do with apache since it happens with the CLI
interface too.
Reproduce code:
---------------
With an empty postgresql installation, I created an empty database,
connected to it, created an user and set all privileges on this new
database to this user.
Connected as the new user on the new database I created some tables.
When trying to access this new tables with PHP and ADOdb classes, I got a
segmentation fault. At the very end, when running with strace, I got a
message before the segmentation fault saying:
'pg_class access denied'
When I grant read access on this table to the new user, I got:
'pg_attribute access denied' and so on...
When I grant read access to all pg_* tables, the problem disappear and PHP
runs ok.
Expected result:
----------------
PgSQL Error: Access denied to pg_* system table
or something like that.
Actual result:
--------------
Segmentation Fault if the connection user has no read access on system
tables
