MiracleLinux 7 : postgresql-9.2.23-3.el7 (AXSA:2017-2464:03)
medium Nessus Plugin ID 289139
Synopsis
The remote MiracleLinux host is missing one or more security updates.Description
The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-2464:03 advisory.* Privilege escalation flaws were found in the initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.
(CVE-2017-12172, CVE-2017-15097) Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration (/var/lib/pgsql).
Asianux would like to thank the PostgreSQL project for reporting CVE-2017-12172. The CVE-2017-15097 issue was discovered by Pedro Barbosa (Asianux) and the PostgreSQL project. Upstream acknowledges Antoine Scemama (Brainloop) as the original reporter of these issues.
CVE-2017-12172 PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. This often suffices for the database superuser to escalate to root privileges when root starts the server.
