Security Vulnerabilities
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to gain privilege escalation via the Navigator for i debugger. This could allow the attacker to access or manipulate sensitive data on the system, or create new profiles with elevated privileges on the IBM i system.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to generate a stack-based buffer overflow in the Native IBM i JSSE provider, caused by improper bounds checking during TLS session establishment. A local attacker could overflow a fixed-length buffer and execute arbitrary code on the system or cause the JVM process to crash.
