What is CVE-2006-4447?

Local users can exploit the inadequacy in the handling of return values from setuid and seteuid system calls within X.Org and XFree86 components. This allows attackers to potentially escalate their privileges by triggering failures in these calls, particularly by manipulating system limits such as ulimit. This vulnerability affects various components including libX11, xdm, xf86dga, xinit, xload, xtrans, and xterm, highlighting the importance of privilege management in Unix-based systems.
