medium Nessus Plugin ID 141947

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of tested product installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1549 advisory.

 - In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server process may exit when a well-formed read-only request produces a particular answer. This can lead to disruption for users of the server. (CVE-2018-11782)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update subversion' to update your system.
