Scientific Linux Security Update : log4j on SL7.x (noarch) (20170807)

critical Nessus Plugin ID 102666
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 Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

- It was found that when using remote logging with log4j socket server the log4j server would deserialize any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log event that, during deserialization, would execute arbitrary code in the context of the logger application. (CVE-2017-5645)

Solution

Update the affected log4j, log4j-javadoc and / or log4j-manual packages.
