Descriptions

Multiple stack-based buffer overflows in json parsing in PostgreSQL before 9.3.x before 9.3.10 and 9.4.x before 9.4.5 allow attackers to cause a denial of service (server crash) via unspecified vectors, which are not properly handled in (1) json or (2) jsonb values.

Múltiple desbordamiento de buffer basado en pila en el análisis gramatical de json en PostgreSQL en versiones anteriores a 9.3.x en versiones anteriores a 9.3.10 y 9.4.x en versiones anteriores a 9.4.5 permite a atacantes provocar una denegación de servicio (caída del servidor) a través de vectores no especificados, los cuales no son manejados adecuadamente en valores (1) json o (2) jsonb.

A stack overflow flaw was discovered in the way the PostgreSQL core server processed certain JSON or JSONB input. An authenticated attacker could possibly use this flaw to crash the server backend by sending specially crafted JSON or JSONB input.

PostgreSQL is an advanced object-relational database management system. A memory leak error was discovered in the crypt() function of the pgCrypto extension. An authenticated attacker could possibly use this flaw to disclose a limited amount of the server memory. A stack overflow flaw was discovered in the way the PostgreSQL core server processed certain JSON or JSONB input. An authenticated attacker could possibly use this flaw to crash the server backend by sending specially crafted JSON or JSONB input.
