Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU6892
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7484
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper privilege checking before providing information from pg_statistic. A remote attacker can send a specially crafted request to bypass SELECT privilege checks, cause memory leak and steal some information from ostensibly restricted tables.
Successful exploitation of the vulnerability results in information disclosure.
Install update from vendor's website.

No. We are not aware of malware exploiting this vulnerability.
2) Man-in-the-middle attack
EUVDB-ID: #VU6893
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7485
CWE-ID:
CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to conduct a man-in-the-middle attack.
The weakness exists in the PGREQUIRESSL environment due to no enforcement of a SSL/TLS connection to a PostgreSQL server. A remote attacker can launch a man-in-the-middle attack to strip the SSL/TLS protection from a connection between a client and a server and modify the communicated data.
Successful exploitation of the vulnerability results in unauthorized access to sensitive information.

3) Information disclosure
EUVDB-ID: #VU6894
Risk: Low
CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7486
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper implementation of pg_user_mappings access qualifications. A remote attacker with USAGE privilege on the associated foreign server can send a specially crafted request to trigger memory leak in pg_user_mappings view and disclose foreign server passwords.
Successful exploitation of the vulnerability results in information disclosure.
