Memory leak in xinetd 2.3.10 allows remote attackers to cause a denial of service (memory consumption) via a large number of rejected connections.

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.

Multiple vulnerabilities in xinetd 2.3.0 and earlier, and additional variants until 2.3.3, may allow remote attackers to cause a denial of service or execute arbitrary code, primarily via buffer overflows or improper NULL termination.
