Alpine: openssh: security update to 9.0_p1-r5
critical Tenable Cloud Security Plugin ID 408306
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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. For example, there is an effective attack against SSH's use of
ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in [email protected] and
(if CBC is used) the [email protected] MAC algorithms. This also affects Maverick Synergy Java SSH API

- 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.
