postgresql-8.4 - new minor release

Several vulnerabilities were discovered in PostgreSQL, a relational
database server system. The 8.4 branch is EOLed upstream, but still
present in Debian squeeze. This new LTS minor version contains the
fixes that were applied upstream to the 9.0.19 version, backported to
8.4.22 which was the last version officially released by the PostgreSQL
developers. This LTS effort for squeeze-lts is a community project
sponsored by credativ GmbH.

• CVE-2014-8161
  Information leak
  A user with limited clearance on a table might have access to information
  in columns without SELECT rights on through server error messages.
• CVE-2015-0241
  Out of boundaries read/write
  The function to_char() might read/write past the end of a buffer. This
  might crash the server when a formatting template is processed.
• CVE-2015-0243
  Buffer overruns in contrib/pgcrypto
  The pgcrypto module is vulnerable to stack buffer overrun that might
  crash the server.
• CVE-2015-0244
  SQL command injection
  Emil Lenngren reported that an attacker can inject SQL commands when the
  synchronization between client and server is lost.

For Debian 6 Squeeze, these issues have been fixed in postgresql-8.4 version 8.4.22lts1-0+deb6u1
