libxstream-java vulnerabilities
==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in XStream.<\/p>\n
Software Description:
– libxstream-java: Java library to serialize objects to XML and back again<\/p>\n
Details:<\/p>\n
It was discovered that XStream incorrectly handled parsing of certain
crafted XML documents. A remote attacker could possibly use this issue to
read arbitrary files. (CVE-2016-3674)<\/p>\n
Zhihong Tian and Hui Lu found that XStream was vulnerable to remote code
execution. A remote attacker could run arbitrary shell commands by
manipulating the processed input stream. (CVE-2020-26217)<\/p>\n
It was discovered that XStream was vulnerable to server-side forgery
attacks. A remote attacker could request data from internal resources
that are not publicly available only by manipulating the processed input
stream. (CVE-2020-26258)<\/p>\n
It was discovered that XStream was vulnerable to arbitrary file deletion
on the local host. A remote attacker could use this to delete arbitrary
known files on the host as long as the executing process had sufficient
rights only by manipulating the processed input stream. (CVE-2020-26259)<\/p>\n
It was discovered that XStream was vulnerable to denial of service,
arbitrary code execution, arbitrary file deletion and server-side forgery
attacks. A remote attacker could cause any of those issues by
manipulating the processed input stream. (CVE-2021-21341, CVE-2021-21342,
CVE-2021-21343, CVE-2021-21344, CVE-2021-21345, CVE-2021-21346,
CVE-2021-21347, CVE-2021-21348, CVE-2021-21349, CVE-2021-21350,
CVE-2021-21351)<\/p>\n

The problem can be corrected by updating your system to the following
package versions:<\/p>\n
Ubuntu 16.04 LTS
