Does anyone know if the NetScaler VPX 13 is vulnerable to the following OpenSSH vulnerabilities


OpenSSH: OpenSSH scp Command Injection Vulnerability


scp in OpenSSH allows command injection in scp.c remote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows."


OpenSSH: Double-Free Memory Corruption Vulnerability


CVSS 4.6

ssh-agent in OpenSSH has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host.


OpenSSH: Information Leak Vulnerability


CVSS 4.3

The client side in OpenSSH has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client).


Thanks in advance
