Buffer overflow in Linux autofs module through long directory names allows local users to perform a denial of service.

Denial of service in Linux 2.0.36 allows local users to prevent any server from listening on any non-privileged port.

The ugidd RPC interface, by design, allows remote attackers to enumerate valid usernames by specifying arbitrary UIDs that ugidd maps to local user and group names.

Linux 2.1.132 and earlier allows local users to cause a denial of service (resource exhaustion) by reading a large buffer from a random device (e.g. /dev/urandom), which cannot be interrupted until the read has completed.

ICMP messages to broadcast addresses are allowed, allowing for a Smurf attack that can cause a denial of service.

Oversized ICMP ping packets can result in a denial of service, aka Ping o' Death.

The suidperl and sperl program do not give up root privileges when changing UIDs back to the original users, allowing root access.
