Description: Two vulnerabilities have been reported in PostgreSQL, which can be exploited by malicious users to cause a DoS (Denial of Service) or gain escalated privileges. 1) A validation error exists within the handling of the SET ROLE command when restoring the previous role setting after an error. This can be exploited by an authenticated user to gain superuser privileges. The vulnerability has been reported in the 8.1 branch. 2) An error in the SET SESSION AUTHORIZATION command can be exploited to crash the server process, if it has been compiled with Asserts enabled. The vulnerability has been reported in the 7.3, 7.4, 8.0 and 8.1 branch. Solution: Update to the fixed versions. http://www.postgresql.org/download/ Version 7.3.x: Update to version 7.3.14.
