========================================================================== Ubuntu Security Notice USN-4714-1 January 28, 2021
libxstream-java vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS - Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in libxstream-java.
Software Description: - libxstream-java: Java library to serialize objects to XML and back again
Details:
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 had sufficient rights only by manipulating the processed input stream. (CVE-2020-26259)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04 LTS: libxstream-java 1.4.11.1-1ubuntu0.1
Ubuntu 18.04 LTS: libxstream-java 1.4.11.1-1~18.04.1
In general, a standard system update will make all the necessary changes.
