Description Thomas Leroy 2022-09-19 11:48:09 UTC
CVE-2022-40156

Those using Xstream to seralize XML data may be vulnerable to Denial of Service
attacks (DOS). If the parser is running on user supplied input, an attacker may
supply content that causes the parser to crash by stackoverflow. This effect may
support a denial of service attack.
