Synopsis
The remote database server is affected by multiple vulnerabilities.Description
The version of PostgreSQL installed on the remote host is 9.2.x prior to 9.2.21, 9.3.x prior to 9.3.17, 9.4.x prior to 9.4.12, 9.5.x prior to 9.5.7, or 9.6.x prior to 9.6.3. It is, therefore, affected by multiple vulnerabilities :- A information disclosure vulnerability exists in unspecified selectivity estimation functions due to improper checking of user privileges before providing information from pg_statistics. An authenticated, remote attacker can exploit this to disclose potentially sensitive information from restricted tables.
(CVE-2017-7484)
- A flaw exists because the PGREQUIRESSL environment variable setting is not properly honored, which results in a failure to require appropriate SSL/TLS connections.
A man-in-the-middle attacker can exploit this to cause an insecure, non-SSL/TLS connection between a client and and a server. Note that version 9.2.x is not affected by this vulnerability. (CVE-2017-7485)
- A information disclosure vulnerability exists in the pg_user_mappings view that allows access to user mappings which may contain passwords that have persisted from the CREATE USER MAPPING command. An authenticated, remote attacker who has USAGE privilege on the associated foreign server can exploit this to disclose foreign server passwords. (CVE-2017-7486)
Solution
Upgrade to PostgreSQL version 9.2.21 / 9.3.17 / 9.4.12 / 9.5.7 / 9.6.3 or later.See Also
