Description Lubomir Kundrak 2007-09-27 15:17:46 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2007-3278 to the following vulnerability:

PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Link library (dblink) is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1.

Comment 1 Lubomir Kundrak 2007-09-27 15:19:53 UTC

Red Hat does not consider this do be a security issue. dblink is disabled in
default configuration of PostgreSQL packages as shipped with Red Hat Enterprise
Linux versions 2.1, 3, 4 and 5, and it is a configuration decision whether to
grant local users arbitrary access.
