Babelfish for PostgreSQL vulnerabilities

An out-of-bounds read in the TDS RPC procedure-name parser in the Babelfish for PostgreSQL extension (versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4) and in Amazon Aurora PostgreSQL with Babelfish. A remote authenticated user may read adjacent process memory or cause a denial of service by sending a malformed TDS RPC request to the TDS port (default 1433).

A heap-based buffer overflow in the TDS prelogin parser in the Babelfish for PostgreSQL extension versions 1.0-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish might allow remote attackers to execute arbitrary OS commands as the database process user via a specially crafted malformed TDS prelogin packet to the TDS port. This record consolidates a related NULL-pointer-dereference finding in the same prelogin parser.

Improper access control in the Babelfish for PostgreSQL extension versions 1.2-1.5, 2.1-2.15, 3.1-3.12, 4.0-4.8, 5.1-5.4 and in Amazon Aurora PostgreSQL with Babelfish may allow remote authenticated users to elevate their privileges.
