A security vulnerability and a data loss bug have been found in postgresql-common, Debian's PostgreSQL database cluster management tools.
Dawid Golunski discovered that a symlink in /var/log/postgresql/ could be used by the
postgressystem user to write to arbitrary files on the filesystem the next time PostgreSQL is started by root.
Rafał 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.
