XStream is vulnerable to a Denial of Service attack due to stack overflow from a manipulated binary input stream
### Impact
The vulnerability may allow a remote attacker to terminate the application with a stack overflow error resulting in a denial of service only by manipulating the processed input stream when XStream is configured to use the BinaryStreamDriver.

### Patches
XStream 1.4.21 detects the manipulation in the binary input stream causing the the stack overflow and raises an InputManipulationException instead.

### Workarounds
The only solution is to catch the StackOverflowError in the client code calling XStream if XStream is configured to use the BinaryStreamDriver.

### References
See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for [CVE-2024-47072](https://x-stream.github.io/CVE-2024-47072.html).

Alexis Challande of Trail Of Bits found and reported the issue to XStream and provided the required information to reproduce it.

Denial of Service by injecting highly recursive collections or maps in XStream
The vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream.
