Qualcomm Eudora 5.2.1 has been released recently. Quoting from
http://www.eudora.com/download/eudora/windows/5.2.1/RelNotes.txt :

> Improved guarding against spoofed Attachment Converted: lines.

Attachments can still be spoofed by including a CR (ctrl-M, x0d, ASCII 13)
character anywhere within the "Attachment Converted:" string [these get
converted internally into a NUL (x00) and ignored], e.g.:

Attachments can still be spoofed by including a CR=x0d character anywhere
within the "Attachment Converted:" string (these get converted internally
into a NUL=x00 and ignored), e.g.:

Attachment<CR> Converted: "c:\winnt\system32\calc.exe" NoAttachIcon
Attachment Converted: "c:\winnt\system32\calc.exe" NoAttachIcon

(First line with four-character <CR> marker for the sake of Eudora users.)
