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

  • CVE-2016-5423

    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.

  • CVE-2016-5424

    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 9.1.23-0+deb7u1.

We recommend that you upgrade your postgresql-9.1 packages.
