CVE-1999-0526

Summary

CVE-1999-0526 is a vulnerability affecting X servers where access control is disabled, allowing unauthorized users to connect. This issue arises when an "xhost +" command is executed, disabling the security measure designed to restrict access to the X server. Consequently, anyone can connect to the affected system and potentially gain unauthorized access to the X11 applications running on it. This vulnerability can lead to serious security consequences, such as data theft or unauthorized system modifications. To mitigate this risk, it is essential to ensure that access control for X servers is properly configured and restricted to trusted users or hosts.
