Ethereal UMA dissector denial of service
| ethereal-uma-dissector-dos (26008) |  Low Risk |
Description:
Ethereal is vulnerable to a denial of service, caused by an infinite loop condition in the UMA dissector. A remote attacker could exploit this vulnerability using a malformed packet or trace file to cause the UMA dissector to enter into an infinite loop, resulting in a denial of service.
