USN-6560-1: OpenSSH vulnerabilities

Fabian Bäumer, Marcus Brinkmann, Jörg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being...

FreeBSD : FreeBSD -- ssh-add does not honor per-hop destination constraints (e31a8f8e-47bf-11ee-8e38-002590c1f29c)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the e31a8f8e-47bf-11ee-8e38-002590c1f29c advisory. - ssh-add in OpenSSH before 9.3 adds smartcard keys to ssh-agent without the intended per-hop destinati...

GLSA-202307-01 : OpenSSH: Remote Code Execution

The remote host is affected by the vulnerability described in GLSA-202307-01 OpenSSH: Remote Code Execution - OpenSSH server sshd 9.1 introduced a double-free vulnerability during options.kexalgorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated...

FreeBSD -- ssh-add does not honor per-hop destination constraints

Problem Description: When using ssh-add1 to add smartcard keys to ssh-agent1 with per-hop destination constraints, a logic error prevented the constraints from being sent to the agent resulting in keys being added to the agent without constraints. Impact: A malicious server could leverage the key...

Privilege Escalation

openssh is vulnerable to Privilege Escalation. The vulnerability arises from the library adding smartcard keys to ssh-agent without enforcing the intended per-hop destination constraints. This can result in unauthorized access to the system and the potential disclosure of sensitive information...
