CVE-2016-1255
Dawid Golunski discovered that a symlink in /var/log/postgresql/ could be used by the postgres system user to write to arbitrary files on the filesystem the next time PostgreSQL is started by root.
#614374 Rafal Kupka discovered that pg_upgradecluster did not properly upgrade databases that are owned by a non-login role (or group).
For Debian 7 Wheezy, these problems have been fixed in version 134wheezy5.
We recommend that you upgrade your postgresql-common packages.
