Hi, The following vulnerability was published for libxstream-java. CVE-2022-41966[0]: | XStream serializes Java objects to XML and back again. Versions prior | to 1.4.20 may allow a remote attacker to terminate the application | with a stack overflow error, resulting in a denial of service only via | manipulation 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 issue is patched in version | 1.4.20 which handles the stack overflow and raises an | InputManipulationException instead. A potential workaround for users | who only use HashMap or HashSet and whose XML refers these only as | default map or set, is to change the default implementation of | java.util.Map and java.util per the code example in the referenced | advisory. However, this implies that your application does not care | about the implementation of the map and all elements are comparable. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
