Vulnerability Description
A vulnerability was found in Samba's SMB2 packet signing mechanism.

This flaw allows an attacker to perform attacks, such as a man-in-the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and server, affecting the integrity of the data.
