Ethereal has a buffer overflow in AFS packet parsing
|ethereal-afs-bo (5557)||Medium Risk|
Ethereal is vulnerable to a buffer overflow in the parsing of AFS packets. By sending a specially-crafted AFS packet, an attacker can overflow a buffer in the ACL function and execute arbitrary code on the system.
