CVE-2003-1134: Sun Java

Low severity, CVSS 2.1. EPSS: 0.8% chance of exploitation in the next 30 days.

Sun Java 1.3.1, 1.4.1, and 1.4.2 allows local users to cause a denial of service (JVM crash), possibly by calling the ClassDepth function with a null parameter, which causes a crash instead of generating a null pointer exception.

Affected products

• Sun Java: version 1.3.1 only; version 1.4.1 only; version 1.4.2 only
