high Nessus Plugin ID 161576

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5445-1 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)

 - 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 client sends certain sequences of protocol commands. This can lead to disruption for users of the server. (CVE-2019-0203)

 - Subversion's mod_authz_svn module will crash if the server is using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option and a client sends a request for a non-existing repository URL.
 This can lead to disruption for users of the service. This issue was fixed in mod_dav_svn+mod_authz_svn servers 1.14.1 and mod_dav_svn+mod_authz_svn servers 1.10.7 (CVE-2020-17525)

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