This LTS effort for squeeze-lts is a community project sponsored by credativ GmbH.

Migration to Version 8.4.22lts5

A dump/restore is not required for those running 8.4.X. However, if you are upgrading from a version earlier than 8.4.22, see the relevant release notes.

Security Fixes

Fix contrib/pgcrypto to detect and report too-short crypt salts (Josh Kupershmidt)

Certain invalid salt arguments crashed the server or disclosed a few bytes of server memory. We have not ruled out the viability of attacks that arrange for presence of confidential information in the disclosed bytes, but they seem unlikely. (CVE-2015-5288)");
