COMMAND
Eudora
SYSTEMS AFFECTED
Eudora mail client
PROBLEM
I will cover vew Eudora client vulnerabilities here. Troy Ablan
posted following. At least some versions of Eudora Light prior to
3.0.5 return a Divide by Zero error and immediately close when
trying to pop a message that has a ctime of 0 (Read as Dec 31 1969
19:00 EST (-0500)). This corrupts the .mbx file, and both the
message on the pop server and the .mbx file must be manually
removed (or hacked) in order to proceed.
Chris Owen added following. With version up to at least 3.0.3,
setting the clock forward 100 years will cause Eudora to cause a
segmentation fault when sending mail.
According to Alan Brown, Eudora will also die horribly if it
receives any mail dated prior to Jan 1, 1970.
SOLUTION
John Hardin has just updated his procmail "kit" to shorten long
file names on MIME attachments. This should prevent potential
exploits in mail clients such as Outlook, Outlook Express,
Netscape Mail, and possibly Eudora. John's procmail filter kit
can be found at:
