Descriptions
The bitsubstr function in backend/utils/adt/varbit.c in PostgreSQL 8.0.23, 8.1.11, and 8.3.8 allows remote authenticated users to cause a denial of service (daemon crash) or have unspecified other impact via vectors involving a negative integer in the third argument, as demonstrated by a SELECT statement that contains a call to the substring function for a bit string, related to an "overflow."
La función bitsubstr en backend/utils/adt/varbit.c en PostgreSQL v8.0.23, v8.1.11 y v8.3.8 permite a usuarios remotos autenticados causar una denegación de servicio (cuelgue del demonio) o tener otro impacto no especificado a través de vectores que implican un entero negativo en el tercer argumento, como lo demuestra una instrucción SELECT que contiene una llamada a la función substring de una cadena de bits, relacionado con un desbordamiento.
