A libxstream-java security update has been released for Debian GNU/Linux 8 Extended LTS.

ELA-336-1 libxstream-java security update

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 8 jessie, these problems have been fixed in version 1.4.11.1-1+deb8u1.

We recommend that you upgrade your libxstream-java packages.
