Summary

CVE-2016-0766

A privilege escalation vulnerability for users of PL/Java was
discovered. Certain custom configuration settings (GUCs) for PL/Java
will now be modifiable only by the database superuser to mitigate
this issue.

CVE-2016-0773

Tom Lane and Greg Stark discovered a flaw in the way PostgreSQL
processes specially crafted regular expressions. Very large
character ranges in bracket expressions could cause infinite
loops or memory overwrites. A remote attacker can exploit this
flaw to cause a denial of service or, potentially, to execute
arbitrary code.

For the stable distribution (jessie), these problems have been fixed in
version 9.4.6-0+deb8u1.

We recommend that you upgrade your postgresql-9.4 packages.
