Details

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)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10

• postgresql-9.4 - 9.4.1-0ubuntu0.14.10

Ubuntu 14.04

• postgresql-9.3 - 9.3.6-0ubuntu0.14.04

Ubuntu 12.04

• postgresql-9.1 - 9.1.15-0ubuntu0.12.04

Ubuntu 10.04

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
