postgresql-9.4 - security update

Several vulnerabilities have been found in PostgreSQL-9.4, a SQL
database system.

• 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.
