Eudora URL Handling Buffer Overflow Vulnerability

Secunia Advisory: SA11568
Release Date: 2004-05-07
Critical: Highly critical
Impact: System access
Where: From remote
Software: Eudora 5.x
Eudora 6.x

Paul Szabo has reported a vulnerability in Eudora, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the URL handling functionality. This can be exploited via a malicious email containing a specially crafted overly long link (about 300 bytes).

Successful exploitation allows execution of arbitrary code on a vulnerable system, but requires that the user is tricked into clicking the malicious URL.

The vulnerability has been reported in versions 6.1, 6.0.3, and 5.2.1 for Windows. Other versions may also be affected.

Use another product, since other highly critical vulnerabilities also exist in Eudora.
