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.

The crypt function in contrib/pgcrypto in PostgreSQL before 9.0.23, 9.1.x before 9.1.19, 9.2.x before 9.2.14, 9.3.x before 9.3.10, and 9.4.x before 9.4.5 allows attackers to cause a denial of service (server crash) or read arbitrary server memory via a ‘too-short’ salt.
