CVE-2022-40154 [MEDIUM] CVE-2022-40154 xstream: Xstream to serialise XML data was vulnerable to Denial of Service attacks
CVE-2022-40154 xstream: Xstream to serialise XML data was vulnerable to Denial of Service attacks
Those using Xstream to serialise 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 stack overflow. This effect may support a denial of service attack.
