Vypress < 4.0 First Message Field Overflow

Critical

Synopsis

The remote host is vulnerable to a buffer overflow.

Description

The remote host is running a version of Vypress Messenger, that is vulnerable to a remote buffer overflow. An attacker exploiting this flaw would only need to be able to send a message or file to the Vypress service (listens on port 7777 by default). A successful exploit would allow the remote attacker the ability to overwrite and control the program's memory.

Solution

Upgrade to version 4.0 or higher.
