    Additional Changes:

    This update also fixes several bugs and adds various enhancements. Documentation for these changes is     available from the Release Notes document linked to in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

It was discovered that logback, a flexible logging library for Java, would deserialize data from untrusted sockets which may lead to the execution of arbitrary code. This issue has been resolved by adding a whitelist to use only trusted classes.

For Debian 7 'Wheezy', these problems have been fixed in version 1:1.0.4-1+deb7u1.

We recommend that you upgrade your logback packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - QOS.ch Logback before 1.2.0 has a serialization vulnerability affecting the SocketServer and     ServerSocketReceiver components. (CVE-2017-5929)

Note that Nessus relies on the presence of the package as reported by the vendor.
