Package        : libxstream-java
CVE ID         : CVE-2022-41966
Debian Bug     : 1027754

XStream serializes Java objects to XML and back again. Versions prior to
1.4.15-3+deb11u2 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 the stable distribution (bullseye), this problem has been fixed in
version 1.4.15-3+deb11u2.

We recommend that you upgrade your libxstream-java packages.
