Package : libxstream-java
Version : 1.4.11.1-1+deb10u4
CVE ID : CVE-2022-41966
Debian Bug : 1027754

XStream serializes Java objects to XML and back again. Versions prior to
1.4.11.1-1+deb10u4 may allow a remote attacker to terminate the application
with a stack overflow error, resulting in a denial of service only via
manipulation of the processed input stream. The attack uses the hash code
implementation for collections and maps to force recursive hash calculation
causing a stack overflow. This update handles the stack overflow and raises an
InputManipulationException instead.

For Debian 10 buster, this problem has been fixed in version
1.4.11.1-1+deb10u4.

We recommend that you upgrade your libxstream-java packages.
