CGA-723m-w75j-48wv

Summary

XStream is vulnerable to a Denial of Service attack due to stack overflow from a manipulated binary input stream

Description

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.
