The PostgreSQL Global Development Group has released an update to all supported
versions of the PostgreSQL database system, including 10.3, 9.6.8, 9.5.12,
9.4.17, and 9.3.22.
The purpose of this release is to address CVE-2018-1058, which describes how a
user can create like-named objects in different schemas that can change the
behavior of other users' queries and cause unexpected or malicious behavior,
also known as a "trojan-horse" attack. Most of this release centers around added
documentation that describes the issue and how to take steps to mitigate the
impact on PostgreSQL databases.
We strongly encourage all of our users to please visit
