functions. An authenticated attacker could possibly use this issue to
escalate their privileges. (CVE-2014-0061)

CREATE INDEX statements. An authenticated attacker could possibly use this
issue to obtain access to restricted data, bypassing intended privileges.

input. 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-2014-0063)

calculations. 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-2014-0064)

Peter Eisentraut and Jozef Mlich discovered that PostgreSQL incorrectly
handled certain buffer sizes. 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-2014-0065)

Honza Horak discovered that PostgreSQL incorrectly used the crypt() library
function. This issue could possibly cause PostgreSQL to crash, resulting in
a denial of service (CVE-2014-0066)
