Debian — Security Information — DSA-5315-1 libxstream-java
Created on January 22, 2023 at 4:50 pm
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.
