critical Nessus Plugin ID 289686
Synopsis
The remote MiracleLinux host is missing one or more security updates.Description
The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-2281:02 advisory.* It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords. (CVE-2017-7546)
* An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so.
(CVE-2017-7547)
* An authorization flaw was found in the way PostgreSQL handled large objects.
A remote, authenticated attacker with no privileges on a large object could potentially use this flaw to overwrite the entire content of the object, thus resulting in denial of service. (CVE-2017-7548) Asianux would like to thank the PostgreSQL project for reporting these issues.
Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van der Ham as the original reporters of CVE-2017-7546; Jeff Janes as the original reporter of CVE-2017-7547; and Chapman Flack as the original reporter of CVE-2017-7548.
CVE-2017-7546 PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to incorrect authentication flaw allowing remote attackers to gain access to database accounts with an empty password.
CVE-2017-7547 PostgreSQL versions before 9.2.22, 9.3.18, 9.4.13, 9.5.8 and 9.6.4 are vulnerable to authorization flaw allowing remote authenticated attackers to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so.
