Description:
Donato Ferrante has discovered a vulnerability in PSOProxy, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error when handling received data. This can be exploited to cause a buffer overflow by sending an overly long HTTP request or arbitrary large string (about 1035 bytes) to the service or tricking a user, whose traffic is processed by the proxy, to visit a malicious website or click a specially crafted link.

The vulnerability has been confirmed in version 0.91 for Windows. Other versions may also be affected.

Solution:
Use another product.
