Several vulnerabilities have been discovered in PostgreSQL, an SQL database system. The Common Vulnerabilities and Exposures project identifies the following problems: Authenticated users can shut down the backend server by re-LOAD-ing libraries in $libdir/plugins, if any libraries are present there. (The old stable distribution (etch) is not affected by this issue.) Authenticated non-superusers can gain database superuser privileges if they can create functions and tables due to incorrect execution of functions in functional indexes. If PostgreSQL is configured with LDAP authentication, and the LDAP configuration allows anonymous binds, it is possible for a user to authenticate themselves with an empty password. (The old stable distribution (etch) is not affected by this issue.) In addition, this update contains reliability improvements which do not target security issues.
