Debian DLA-2507-1 : libxstream-java security update

high Nessus Plugin ID 144681

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several security vulnerabilities were discovered in XStream, a Java library to serialize objects to XML and back again.

CVE-2020-26258

XStream is vulnerable to a Server-Side Forgery Request which can be activated when unmarshalling. The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream.

CVE-2020-26259

Xstream is vulnerable to an Arbitrary File Deletion on the local host when unmarshalling. The vulnerability may allow a remote attacker to delete arbitrary known files on the host as long as the executing process has sufficient rights only by manipulating the processed input stream.

For Debian 9 stretch, these problems have been fixed in version 1.4.11.1-1+deb9u1.

We recommend that you upgrade your libxstream-java packages.

For the detailed security status of libxstream-java please refer to its security tracker page at:

Solution
