Wireshark (Ethereal) XOT dissector denial of service
| wireshark-xot-dos (29843) |  Medium Risk |
Description:
Wireshark (formerly known as Ethereal) is vulnerable to a denial of service attack, caused by an unspecified vulnerability in the XOT dissector. A remote attacker could exploit this vulnerability using a malformed packet or trace file to cause the application to consume all available memory resources, resulting in a denial of service.
