"Stephen Frost discovered that PostgreSQL incorrectly displayed certain
values in error messages. An authenticated user could gain access to
seeing certain values, contrary to expected permissions.
(CVE-2014-8161)

Andres Freund, Peter Geoghegan and Noah Misch discovered that
PostgreSQL incorrectly handled buffers in to_char functions. An
authenticated attacker could possibly use this issue to cause
PostgreSQL to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2015-0241)

It was discovered that PostgreSQL incorrectly handled memory in the
pgcrypto extension. An authenticated attacker could possibly use this
issue to cause PostgreSQL to crash, resulting in a denial of service,
or possibly execute arbitrary code. (CVE-2015-0243)

Emil Lenngren discovered that PostgreSQL incorrectly handled extended
protocol message reading. An authenticated attacker could possibly use
this issue to cause PostgreSQL to crash, resulting in a denial of
service, or possibly inject query messages. (CVE-2015-0244).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
