Apple Safari Cross-Domain Cookie Injection Vulnerability

Affected Software:   
Safari 3.x
Safari for Windows 3.x

A vulnerability has been discovered in Apple Safari, which can be exploited by malicious people to bypass certain security restrictions.

The problem is that websites are allowed to set cookies for certain country-specific secondary top-level domains. This can e.g. be exploited to fix a session by setting a known session ID in a cookie, which the browser sends to all web sites operating under an affected domain (e.g. co.uk, com.au).

The vulnerability is confirmed in Apple Safari for Windows 3.1.2. Other versions may also be affected.

Solution:  Do not browse untrusted web sites or follow untrusted links.
