The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an
insufficiently trustworthy search path, leading to remote code execution
if an agent is forwarded to an attacker-controlled system.
(CVE-2023-38408)
Prefix Truncation Attacks in SSH Specification (Terrapin Attack).
(CVE-2023-48795)
In ssh-agent in OpenSSH before 9.6, certain destination constraints can
be incompletely applied. When destination constraints are specified
during addition of PKCS#11-hosted private keys, these constraints are
only applied to the first key, even if a PKCS#11 token returns multiple
keys. (CVE-2023-51384)
In ssh in OpenSSH before 9.6, OS command injection might occur if a user
name or host name has shell metacharacters, and this name is referenced
by an expansion token in certain situations. For example, an untrusted
Git repository can have a submodule with shell metacharacters in a user
name or host name. (CVE-2023-51385)");
