      <title>CVE-2021-39139 — XStream is vulnerable to an Arbitrary Code Execution attack</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2021-39139</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; x-stream xstream&lt;/p&gt;
&lt;p&gt;XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream. A user is only affected if using the version out of the box with JDK 1.7u21 or below. However, this scenario can be adjusted easily to an external Xalan that works regardless of the version of the Java runtime. No user is affected, who followed the recommendation to setup XStream&amp;#39;s security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.&lt;/p&gt;</description>

      <link>https://vulnerability.circl.lu/vuln/usn-5946-1</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Ubuntu:Pro:14.04:LTS: libxstream-java, Ubuntu:Pro:16.04:LTS: libxstream-java, Ubuntu:18.04:LTS: libxstream-java, Ubuntu:20.04:LTS: libxstream-java, Ubuntu:22.04:LTS: libxstream-java&lt;/p&gt;
&lt;p&gt;Lai Han discovered that XStream incorrectly handled certain inputs.
If a user or an automated system were tricked into opening a specially crafted
input file, a remote attacker could possibly use this issue to cause a denial
of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
(CVE-2021-39140)&lt;/p&gt;
&lt;p&gt;It was discovered that XStream incorrectly handled certain inputs. If
a user or an automated system were tricked into opening a specially crafted
input file, a remote attacker could possibly use this issue to execute
arbitrary code. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04
LTS. (CVE-2021-39139, CVE-2021-39141, CVE-2021-39144, CVE-2021-39145,
