Package        : postgresql-9.4
CVE ID         : CVE-2016-0766 CVE-2016-0773

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.
