This update fixes CVE-2014-0060, in which PostgreSQL did not
properly enforce the WITH ADMIN OPTION permission for ROLE management.
Before this fix, any member of a ROLE was able to grant others access
to the same ROLE regardless if the member was given the WITH ADMIN
OPTION permission. It also fixes multiple privilege escalation issues,
including: CVE-2014-0061, CVE-2014-0062, CVE-2014-0063, CVE-2014-0064,
CVE-2014-0065, and CVE-2014-0066. More information on these issues can
be found on our security page and the security issue detail wiki page.
With this release, we are also alerting users to a known security hole
that allows other users on the same machine to gain access to an
operating system account while it is doing "make check":
CVE-2014-0067. "Make check" is normally part of building PostgreSQL
from source code. As it is not possible to fix this issue without
causing significant issues to our testing infrastructure, a patch will
be released separately and publicly. Until then, users are strongly
advised not to run "make check" on machines where untrusted users have
accounts.
