- 漏洞讨论

Multiple remote buffer overflow vulnerabilities affect Xzabite's dyndnsupdate. These issues are due to a failure of the application to properly validate the length of user-supplied strings prior to copying them into static process buffers.

An attacker may exploit these issues to execute arbitrary code with the privileges of a user that activated the vulnerable application. This may facilitate unauthorized access or privilege escalation.
