USN-6978-1: XStream vulnerabilities

Publication date

22 August 2024

Overview

Several security issues were fixed in XStream.

Releases

Packages

  • libxstream-java - Java library to serialize objects to XML and back again

Details

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)

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)

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)

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...

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)

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)

Update instructions

In general, a standard system update will make all the necessary changes.
