https://notcve.org/view.php?id=CVE-2015-3165
Double free vulnerability in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 allows remote attackers to cause a denial of service (crash) by closing an SSL session at a time when the authentication timeout will expire during the session shutdown sequence. Vulnerabilidad de doble liberación en PostgreSQL anterior a 9.0.20, 9.1.x anterior a 9.1.16, 9.2.x anterior a 9.2.11, 9.3.x anterior a 9.3.7, y 9.4.x anterior a 9.4.2 permite a atacantes remotos causar una denegación de servicio (caída) mediante el cierre de una sesión SSL en un momento cuando el fin de sesión de la autenticación caducará durante la secuencia del cierre de sesión. A double-free flaw was found in the way PostgreSQL handled connections. An unauthenticated attacker could possibly exploit this flaw to crash the PostgreSQL backend by disconnecting at approximately the same time as the authentication time out was triggered. • http://lists.apple.com/archives/security-announce/2015/Sep/msg00004.html http://rhn.redhat.com/errata/RHSA-2015-1194.html http://rhn.redhat.com/errata/RHSA-2015-1195.html http://rhn.redhat.com/errata/RHSA-2015-1196.html http://www.debian.org/security/2015/dsa-3269 http://www.debian.org/security/2015/dsa-3270 http://www.postgresql.org/about/news/1587 http://www.postgresql.org/docs/9.0/static/release-9-0-20.html http://www.postgresql.org/docs/9.1/static • CWE-416: Use After Free •
CVSS: 9.8EPSS: 1%CPEs: 12EXPL: 0CVE-2015-3166 – postgresql: unanticipated errors from the standard library
https://notcve.org/view.php?id=CVE-2015-3166
The snprintf implementation in PostgreSQL before 9.0.20, 9.1.x before 9.1.16, 9.2.x before 9.2.11, 9.3.x before 9.3.7, and 9.4.x before 9.4.2 does not properly handle system-call errors, which allows attackers to obtain sensitive information or have other unspecified impact via unknown vectors, as demonstrated by an out-of-memory error. La implementación de snprintf en PostgreSQL versiones anteriores a 9.0.20, versiones 9.1.x anteriores a 9.1.16, versiones 9.2.x anteriores a 9.2.11, versiones 9.3.x anteriores a 9.3.7 y versiones 9.4.x anteriores a 9.4.2, no maneja apropiadamente los errores de llamadas al sistema , lo que permite a atacantes obtener información confidencial o tener otro impacto no especificado por medio de vectores desconocidos, como es demostrado por un error fuera de la memoria. It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system was in a state that would cause the standard library functions to fail (for example, memory exhaustion), an authenticated user could possibly exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file. • http://ubuntu.com/usn/usn-2621-1 http://www.debian.org/security/2015/dsa-3269 http://www.debian.org/security/2015/dsa-3270 http://www.postgresql.org/about/news/1587 http://www.postgresql.org/docs/9.0/static/release-9-0-20.html http://www.postgresql.org/docs/9.1/static/release-9-1-16.html http://www.postgresql.org/docs/9.2/static/release-9-2-11.html http://www.postgresql.org/docs/9.3/static/release-9-3-7.html http://www.postgresql.org/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-391: Unchecked Error Condition •

It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key. This could potentially help an authenticated user to launch a possible cryptographic attack, although no suitable attack is currently known. • http://ubuntu.com/usn/usn-2621-1 http://www.debian.org/security/2015/dsa-3269 http://www.debian.org/security/2015/dsa-3270 http://www.postgresql.org/about/news/1587 http://www.postgresql.org/docs/9.0/static/release-9-0-20.html http://www.postgresql.org/docs/9.1/static/release-9-1-16.html http://www.postgresql.org/docs/9.2/static/release-9-2-11.html http://www.postgresql.org/docs/9.3/static/release-9-3-7.html http://www.postgresql.org/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-209: Generation of Error Message Containing Sensitive Information •

CVSS: 9.8EPSS: 0%CPEs: 7EXPL: 0CVE-2015-0244 – postgresql: loss of frontend/backend protocol synchronization after an error
https://notcve.org/view.php?id=CVE-2015-0244
PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 does not properly handle errors while reading a protocol message, which allows remote attackers to conduct SQL injection attacks via crafted binary data in a parameter and causing an error, which triggers the loss of synchronization and part of the protocol message to be treated as a new message, as demonstrated by causing a timeout or query cancellation. PostgreSQL versiones anteriores a 9.0.19, versiones 9.1.x anteriores a 9.1.15, versiones 9.2.x anteriores a 9.2.10, versiones 9.3.x anteriores a 9.3.6 y versiones 9.4.x anteriores a 9.4.1, no maneja apropiadamente los errores al leer un mensaje de protocolo, lo que permite a atacantes remotos conducir ataques de inyección SQL por medio de datos binarios diseñados en un parámetro y causar un error, lo que desencadena la pérdida de sincronización y parte del mensaje del protocolo es tratado como un mensaje nuevo, como es demostrado al causar un tiempo de espera o la cancelación de la consulta. A flaw was found in the way PostgreSQL handled certain errors that were generated during protocol synchronization.
