Summary
The host is installed with IBM DB2 and is prone to buffer overflow and TLS renegotiation vulnerabilities.
Insight
Insight
The flaws are due to: - Buffer overflow error within the scalar function 'REPEAT', which could allow malicious users to cause a vulnerable server to crash. - An error in the 'TLS' implementation while handling session 're-negotiations' which can be exploited to insert arbitrary plaintext into an existing TLS session via Man-in-the-Middle (MitM) attacks.
