Descriptions

The to_char function in 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 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a (1) large number of digits when processing a numeric formatting template, which triggers a buffer over-read, or (2) crafted timestamp formatting template, which triggers a buffer overflow.

La función to_char en 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, permite a usuarios autenticados remotos causar una negación de servicio (bloqueo) o posiblemente ejecutar código arbitrario por medio de un (1) gran número de dígitos cuando se procesa una plantilla de formato numérico, que desencadena una lectura excesiva del búfer, o una (2) plantilla de formato de marca de tiempo, que desencadena un desbordamiento del búfer.

A buffer overflow flaw was found in the way PostgreSQL handled certain numeric formatting. An authenticated database user could use a specially crafted timestamp formatting template to cause PostgreSQL to crash or, under certain conditions, execute arbitrary code with the permissions of the user running PostgreSQL.
