postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

Issue Overview: Integer wraparound in PostgreSQL tsvector and tsquery data type functions allows an unprivileged database user to cause the server to undersize an allocation and write out-of-bounds, via crafted large inputs. This may execute arbitrary code as the operating system user running the...
