"A security vulnerability has been found in postgresql-common, Debian's
PostgreSQL database cluster management tools.

CVE-2017-8806

It was discovered that the pg_ctlcluster, pg_createcluster and
pg_upgradecluster commands handled symbolic links insecurely which
could result in local denial of service by overwriting arbitrary
files.

For Debian 7 'Wheezy', these problems have been fixed in version
134wheezy6.

We recommend that you upgrade your postgresql-common packages.

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."
