CVE-2008-5177 describes a critical stack-based buffer overflow vulnerability in Yosemite Backup 8.7, specifically within the DtbClsLogin function, affecting both Linux and Windows platforms. This flaw allows remote, unauthenticated attackers to achieve arbitrary code execution or cause a denial of service by supplying an overly long username during authentication. With a CVSS score of 10.0, this vulnerability presents a severe risk due to its network-based attack vector, low complexity, and complete compromise of confidentiality, integrity, and availability.
