PostgreSQL before 9.1.20, 9.2.x before 9.2.15, 9.3.x before 9.3.11, 9.4.x before 9.4.6, and 9.5.x before 9.5.1 does not properly restrict access to unspecified custom configuration settings (GUCS) for PL/Java, which allows attackers to gain privileges via unspecified vectors.
It was discovered that certain SQL statements containing CASE/WHEN commands could crash the PostgreSQL server, or disclose a few bytes of server memory, potentially leading to arbitrary code execution.
PostgreSQL before 9.1.20, 9.2.x before 9.2.15, 9.3.x before 9.3.11, 9.4.x before 9.4.6, and 9.5.x before 9.5.1 allows remote attackers to cause a denial of service (infinite loop or buffer overflow and crash) via a large Unicode character range in a regular expression.
It was found that PostgreSQL client programs mishandle database and role names containing newlines, carriage returns, double quotes, or backslashes. By crafting such an object name, roles with the CREATEDB or CREATEROLE option could escalate their privileges to superuser when a superuser next executes maintenance with a vulnerable program. Vulnerable programs include pgdumpall, pgupgrade, vacuumdb, reindexdb, and clusterdb.
