New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in PostgreSQL, a SQL database system. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2009-3229 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.)

- CVE-2009-3230 Authenticated non-superusers can gain database superuser privileges if they can create functions and tables due to incorrect execution of functions in functional indexes.

- CVE-2009-3231 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.

Solution

Upgrade the PostgreSQL packages.

For the old stable distribution (etch), these problems have been fixed in version 7.4.26-0etch1 of the postgresql-7.4 source package, and version 8.1.18-0etch1 of the postgresql-8.1 source package.

For the stable distribution (lenny), these problems have been fixed in version 8.3.8-0lenny1 of the postgresql-8.3 source package.
