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.
