(Red Hat Issues Fix) PostgreSQL Bugs Let Remote Authenticated Users Access Systems and Obtain Potentially Sensitive Information from System Memory
SecurityTracker Alert ID:  1041551
SecurityTracker URL:  http://securitytracker.com/id/1041551
CVE Reference:   CVE-2018-10915   (Links to External Site)
Date:  Aug 23 2018
Impact:   Disclosure of system information, Disclosure of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Two vulnerabilities were reported in PostgreSQL. A remote authenticated user can obtain potentially sensitive information on the target system. A remote authenticated user can gain access to the target system.

A remote authenticated user can exploit a flaw in 'libpq' to gain access to other systems without authenticating to those systems [CVE-2018-10915].

Andrew Krasichkov reported this vulnerability.

A remote authenticated user that can issue a 'CREATE TABLE' command can execute a specially crafted 'upsert' command to read arbitrary portions of system memory [CVE-2018-10925].

Impact:   A remote authenticated user can obtain potentially sensitive information from system memory.

A remote authenticated user can gain access to the target system.

Solution:   Red Hat has issued a fix for CVE-2018-10915.
