Amazon Linux AMI : tomcat-native (ALAS-2018-965)

medium Nessus Plugin ID 107236

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Mishandling of client certificates can allow for OCSP check bypass :

When parsing the AIA-Extension field of a client certificate, Apache Tomcat Native Connector 1.2.0 to 1.2.14 and 1.1.23 to 1.1.34 did not correctly handle fields longer than 127 bytes. The result of the parsing error was to skip the OCSP check. It was therefore possible for client certificates that should have been rejected (if the OCSP check had been made) to be accepted. Users not using OCSP checks are not affected by this vulnerability. (CVE-2017-15698)

Solution

Run 'yum update tomcat-native' to update your system.
