efingerd reverse-lookup buffer overflow
|efingerd-reverse-lookup-bo (8380)||High Risk|
efingerd is vulnerable to a buffer overflow caused by improper bounds checking of the hostname by the reverse-lookup function. By connecting to efingerd with a hostname containing 100 bytes or more, a remote attacker can overflow a buffer and execute arbitrary code on the system, typically as a "nobody" user.
