Package : libxstream-java
Version : 1.4.11.1-1+deb9u1
CVE ID : CVE-2020-26258 CVE-2020-26259
Debian Bug : 977625 977624
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.
