PostgreSQL versions 8.0.6 and 8.1.2 have been released fixing a remote denial of service vulnerability on the win32 platform.
Details ------- Vulnerability type: Denial of service Remotely exploitable: YesAffected versions: PostgreSQL 8.0.0-8.0.5, 8.1.0-8.1.1 Fixed versions: PostgreSQL 8.0.6, 8.1.2
Affected platforms: Win32 Non-affected platforms: All non-win32, including Unix, MacOS X and Cygwin.CVE: CVE-2006-0105 (http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2006-0105)
Vulnerability description -------------------------When the postmaster process detects too many attempted connections at the same time, it will incorrectly log a FATAL error and shut down. This will not affect existing processes, but will make it impossible to initiate new connections until the service is restarted.
This is a denial of service vulnerability only. As it is a standard emergency shutdown, it can not be exploited for remote code execution.
Solution --------Upgrade to version 8.0.6 or 8.1.2 respectively, available from http://www.postgresql.org/ftp/ in both source and binary formats.
Workarounds -----------Implementing proper firewalling at the network and host level will help mitigate this vulnerability. No other workarounds are possible.
