PostgreSQL Minor Versions 8.1.2, 8.0.6 Released
January 9, 2006[From PostgreSQL]
PostgreSQL minor versions 8.1.2 and 8.0.6 are available today. The fixes in the 8.1 and 8.0 branches are critical, especially for Windows users, and users of these branches are urged to update at their earliest opportunity.
One critical fix repairs a denial-of-service vulnerability: on Windows only, the postmaster will exit if too many connection requests arrive simultaneously. This does not affect existing database connections, but will prevent new connections from being established until the postmaster is manually restarted. The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2006-0105 to this issue.
