PostgreSQL 8.4 < 8.4.17 / 9.0 < 9.0.13 / 9.1 < 9.1.9 / 9.2 < 9.2.4 Predictable Random Number Generator

high Nessus Plugin ID 65856
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote database server is affected by an issue in the random number generator.

Description

The version of PostgreSQL installed on the remote host is 8.4.x prior to 8.4.17, 9.0.x prior to 9.0.13, 9.1.x prior to 9.1.9, or 9.2.x prior to 9.2.4. As such, it is potentially affected by an issue where random numbers generated by contrib/pgcrypto functions may be easy for another database user to guess.

Solution

Upgrade to PostgreSQL 8.4.17 / 9.0.13 / 9.1.9 / 9.2.4 or later.
