"It was discovered that dbconfig-common could, depending on the local
umask, make PostgreSQL database backups that were readable by other
users than the database owner. The issue is fixed in version
1.8.46+squeeze.1. Access rights to existing database backups (not only
for PostgreSQL) will be limited to the owner of the backup during the
upgrade of dbconfig-common to this version. Future upgrades will not
change access rights in case the local administrator has specific
requirements.

dbconfig-common is a Debian helper package that is used by a number of
packages to manage the corresponding database.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
