Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : postgresql-8.1, postgresql-8.3 vulnerabilities (USN-834-1)

medium Nessus Plugin ID 41045

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that PostgreSQL could be made to unload and reload an already loaded module by using the LOAD command. A remote authenticated attacker could exploit this to cause a denial of service. This issue did not affect Ubuntu 6.06 LTS. (CVE-2009-3229)

Due to an incomplete fix for CVE-2007-6600, RESET ROLE and RESET SESSION AUTHORIZATION operations were allowed inside security-definer functions. A remote authenticated attacker could exploit this to escalate privileges within PostgreSQL. (CVE-2009-3230)

It was discovered that PostgreSQL did not properly perform LDAP authentication under certain circumstances. When configured to use LDAP with anonymous binds, a remote attacker could bypass authentication by supplying an empty password. This issue did not affect Ubuntu 6.06 LTS. (CVE-2009-3231).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
