A vulnerability was found in Jettison, where parsing an untrusted XML or JSON data may lead to a crash. If the parser is running on user-supplied input, an attacker may supply content that causes the parser to crash, causing memory exhaustion. This effect may support a denial of service attack.

A stack-based buffer overflow vulnerability was found in Jettison, where parsing an untrusted XML or JSON data may lead to a crash. This flaw allows an attacker to supply content that causes the parser to crash by writing outside the memory bounds if the parser is running on user-supplied input, resulting in a denial of service attack.
