17th September 2020: PostgreSQL 13 RC 1 Released!

Minor Versions 8.1.2, 8.0.6 Released

Posted on 2006-01-06

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.

Another critical fix repairs an error in ReadBuffer that can cause data loss due to overwriting recently-added pages. This applies to the 8.1 and 8.0 branches on all platforms.

Other fixes included are:

  • Character string locale comparison bug. This may require a REINDEX on text column indexes in some locales, such as Hungarian.
  • Prevent accidental changes of locale by plperl
  • Two fixes for Japanese encodings
  • Two fixes for COPY CSV
  • Fixes for functions returning RECORD
  • Fixes to autovacuum, dblink and pgcrypto

Full release notes are included in the documentation for the new

version, which is distributed with the source, and will be available within

a few days on PostgreSQL.org.

Versions 7.4.11 and 7.3.13 contain a subset of the fixes above

appropriate to those versions.

Currently, source packages and Windows installer packages are available

for 8.1.2 and 8.0.6. Within a couple of weeks packages for other platforms

will be available from the PostgreSQL Downloads page and other sources.
