It has been reported that Eudora is prone to a denial of service vulnerability when handling e-mail containing excessive MIME nesting. The problem is known to occur when the application attempts to decode the deeply nested message. Successful exploitation of this issue may allow an attacker to cause the application to crash due to corruption of stack memory. It is not known if this issue is further exploitable to execute arbitrary code. It should be noted that this condition may be persistent since the offending message may remain in the client's mail spool. Eudora 6.0.3 is reported to be vulnerable to this issue, however, other versions may be affected as well.
