Multiple buffer overflows in Eudora Worldmail, possibly Worldmail 3 version 6.1.22.0, have unknown impact and attack vectors, as demonstrated by the (1) "Eudora WorldMail stack overflow" and (2) "Eudora WorldMail heap overflow" modules in VulnDisco Pack. NOTE: Some of these details are obtained from third party information. As of 20061118, this disclosure has no actionable information.
