PostgreSQL before 9.1.23, 9.2.x before 9.2.18, 9.3.x before 9.3.14, 9.4.x before 9.4.9, and 9.5.x before 9.5.4 allow remote authenticated users to cause a denial of service (NULL pointer dereference and server crash), obtain sensitive memory information, or possibly execute arbitrary code via (1) a CASE expression within the test value subexpression of another CASE or (2) inlining of an SQL function that implements the equality operator used for a CASE expression involving values of different types. PostgreSQL en versiones anteriores a 9.1.23, 9.2.x en versiones anteriores a 9.2.18, 9.3.x en versiones anteriores a 9.3.14, 9.4.x en versiones anteriores a 9.4.9 y 9.5.x en versiones anteriores a 9.5.4 permiten a usuarios remotos autenticados provocar una denegación de servicio (referencia a puntero NULL y caída del servidor), obtener información de memoria sensible, o posiblemente ejecutar código arbitrario a través de (1) una expresión CASE dentro de la subexpresión de valor de prueba de otro CASE o (2) el inicio de una función SQL que implementa el operador de igualdad utilizado para una expresión CASE que implica valores de diferentes tipos. A flaw was found in the way PostgreSQL server handled certain SQL statements containing CASE/WHEN commands. A remote, authenticated attacker could use a specially crafted SQL statement to cause PostgreSQL to crash or disclose a few bytes of server memory or possibly execute arbitrary code. • http://rhn.redhat.com/errata/RHSA-2016-1781.html http://rhn.redhat.com/errata/RHSA-2016-1820.html http://rhn.redhat.com/errata/RHSA-2016-1821.html http://rhn.redhat.com/errata/RHSA-2016-2606.html http://www.debian.org/security/2016/dsa-3646 http://www.securityfocus.com/bid/92433 http://www.securitytracker.com/id/1036617 https://access.redhat.com/errata/RHSA-2017:2425 https://bugzilla.redhat.com/show_bug.cgi?id=1364001 https://security.gentoo.org/glsa/201701-33 • CWE-476: NULL Pointer Dereference CWE-822: Untrusted Pointer Dereference •
CVSS: 7.6EPSS: 0%CPEs: 47EXPL: 0CVE-2016-5424 – postgresql: privilege escalation via crafted database and role names

PostgreSQL before 9.1.23, 9.2.x before 9.2.18, 9.3.x before 9.3.14, 9.4.x before 9.4.9, and 9.5.x before 9.5.4 might allow remote authenticated users with the CREATEDB or CREATEROLE role to gain superuser privileges via a (1) " (double quote), (2) \ (backslash), (3) carriage return, or (4) newline character in a (a) database or (b) role name that is mishandled during an administrative operation. PostgreSQL en versiones anteriores a 9.1.23, 9.2.x en versiones anteriores a 9.2.18, 9.3.x en versiones anteriores a 9.3.14, 9.4.x en versiones anteriores a 9.4.9 y 9.5.x en versiones anteriores a 9.5.4 podrían permitir a usuarios remotos autenticados con el rol CREATEDB o CREATEROLE obtener privilegios de superusuario a través de un carácter (1) " (comillas dobles), (2) \ (barra invertida), (3) retorno de carro o (4) nueva linea en (a) una base de datos o (b) el nombre del rol que se maneja incorrectamente durante una operación administrativa. A flaw was found in the way PostgreSQL client programs handled database and role names containing newlines, carriage returns, double quotes, or backslashes. By crafting such an object name, roles with the CREATEDB or CREATEROLE option could escalate their privileges to superuser when a superuser next executes maintenance with a vulnerable client program. • http://rhn.redhat.com/errata/RHSA-2016-1781.html http://rhn.redhat.com/errata/RHSA-2016-1820.html http://rhn.redhat.com/errata/RHSA-2016-1821.html http://rhn.redhat.com/errata/RHSA-2016-2606.html http://www.debian.org/security/2016/dsa-3646 http://www.securityfocus.com/bid/92435 http://www.securitytracker.com/id/1036617 https://access.redhat.com/errata/RHSA-2017:2425 https://security.gentoo.org/glsa/201701-33 https://www.postgresql.org/about/news/1688 https: • CWE-20: Improper Input Validation CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 7.5EPSS: 21%CPEs: 28EXPL: 0CVE-2016-0773 – postgresql: case insensitive range handling integer overflow leading to buffer overflow

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the PostgreSQL handling code for regular expressions. A remote attacker could use a specially crafted regular expression to cause PostgreSQL to crash or possibly execute arbitrary code. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177820.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177878.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00056.html http://lists.opensuse.org/opensuse-security-announce& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key.
