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

Open Source Vulnerabilities CVE-2024-47072

XStream is a simple library to serialize objects to XML and back again. This 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. XStream 1.4.21 has been patched to detect the manipulation in the binary input stream causing the the stack overflow and raises an InputManipulationException instead. Users are advised to upgrade. Users unable to upgrade may catch the StackOverflowError in the client code calling XStream if XStream is configured to use the BinaryStreamDriver.

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