Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU6892
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7484
CWE-ID:
Exploit availability:
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.
Update the affected packages.
dev-db/postgresql to version: 9.6.4
Gentoo Linux: All versions
Fixed software versionsCPE2.3 External links
http://security.gentoo.org/glsa/201710-06
Q & A
Can this vulnerability be exploited remotely?
Is there known malware, which exploits this vulnerability?
2) Man-in-the-middle attack
EUVDB-ID: #VU6893
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7485
CWE-ID:
Exploit availability:
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.
Update the affected packages.

3) Information disclosure
EUVDB-ID: #VU6894
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7486
CWE-ID:
Exploit availability:
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.
Update the affected packages.

4) Authentication bypass
EUVDB-ID: #VU7873
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7546
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote attacker to bypass authentication on the target system.
The weakness exists in the systems using libpq or a libpq-based connection driver to perform password-based authentication methods due to insufficient security restrictions. A remote attacker can submit an empty password to disable password login and log in to the system.
Successful exploitation of the vulnerability may result in unauthorized access to the system and further attacks.
Update the affected packages.

EUVDB-ID: #VU7875
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2017-7547
CWE-ID:
Exploit availability:
DescriptionThe vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists in the pg_user_mappings function due to insufficient security restrictions. A remote attacker can gain access to important data and conduct further attacks.
Update the affected packages.
