GCVE-110-MAGEIA-2024-3
Advisory Published
Vulnetix · Advisory published January 8, 2024
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and many other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. This update fixes putty.
