Buffer overflow in internal string handling routines of xinetd before 2.1.8.8 allows remote attackers to execute arbitrary commands via a length argument of zero or less, which disables the length check.

Buffer overflow in Linux xinetd 2.1.8.9pre11-1 and earlier may allow remote attackers to execute arbitrary code via a long ident response, which is not properly handled by the svc_logprint function.

xinetd 2.1.8 and earlier runs with a default umask of 0, which could allow local users to read or modify files that are created by an application that runs under xinetd but does not set its own safe umask.
