Description

Updated libssh2 packages fix a security vulnerability (Terrapin Attack)

The SSH transport protocol with certain OpenSSH extensions, found in

OpenSSH before 9.6 and 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.

Our libssh2 packages were also affected, this update fixes the issue.
