Description

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).

Note that Tenable Network Security has extracted the preceding 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.
