An update that solves one vulnerability can now be installed.

Description:

This update for libssh2_org fixes the following issues:

• Always add the KEX pseudo-methods "ext-info-c" and "kex-strict-c-v00@openssh.com" when configuring custom method list. [bsc#1218971, CVE-2023-48795]

• The strict-kex extension is announced in the list of available KEX methods. However, when the default KEX method list is modified or replaced, the extension is not added back automatically.
