Qualcomm Eudora 5.2

Eudora 5.1 allows remote attackers to bypass security warnings and possibly execute arbitrary code via attachments with names containing a trailing "." (dot).

Eudora before 6.1.1 allows remote attackers to cause a denial of service (crash) via an e-mail with a long "To:" field, possibly due to a buffer overflow.

Qualcomm Eudora 5.1.1, 5.2, and possibly other versions stores email attachments in a predictable location, which allows remote attackers to read arbitrary files via a link that loads an attachment with malicious script into a frame, which then executes the script in the local browser context.
