Title
Unauthenticated Denial-of-Service via Crafted Messages in a Network Protocol Handling Component
Summary
Vulnerabilities exist in a protocol-handling component of AOS-8 and AOS-10 Operating Systems. An unauthenticated attacker could exploit these vulnerabilities by sending specially crafted network messages to the affected service. Due to insufficient input validation, successful exploitation may terminate a critical system process, resulting in a denial-of-service condition.
