[SECURITY] [DLA 592-1] postgresql-9.1 security update

Package        : postgresql-9.1
Version        : 9.1.23-0+deb7u1

Several vulnerabilities have been found in PostgreSQL, an SQL
database system.


    Karthikeyan Jambu Rajaraman discovered that nested CASE-WHEN
    expressions are not properly evaluated, potentially leading to a
    crash or allowing to disclose portions of server memory.


    Nathan Bossart discovered that special characters in database and
    role names are not properly handled, potentially leading to the
    execution of commands with superuser privileges, when a superuser
    executes pg_dumpall or other routine maintenance operations.

For Debian 7 "Wheezy", these problems have been fixed in version

We recommend that you upgrade your postgresql-9.1 packages.
