According to the versions of the openssh packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code     execution when a ProxyCommand is used.(CVE-2025-61985)

    ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly     untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted     sources are the command line and %-sequence expansion of a configuration file. (A configuration file that     provides a complete literal username is not categorized as an untrusted source.)(CVE-2025-61984)

    A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle     attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how     OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be     considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning     the attack complexity high.(CVE-2025-26465)

    In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation     stating that it disables X11 and agent forwarding.(CVE-2025-32728)

The version of AHV installed on the remote host is prior to 11.0.0.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-11.0.0.2 advisory.

  - A flaw was found in libssh when using the ChaCha20 cipher with the OpenSSL library. If an attacker manages     to exhaust the heap space, this error is not detected and may lead to libssh using a partially initialized     cipher context. This occurs because the OpenSSL error code returned aliases with the SSH_OK code,     resulting in libssh not properly detecting the error returned by the OpenSSL library. This issue can lead     to undefined behavior, including compromised data confidentiality and integrity or crashes.
    (CVE-2025-5987)

  - A vulnerability has been found in GNU Binutils 2.45. The affected element is the function elf_swap_shdr in     the library bfd/elfcode.h of the component Linker. The manipulation leads to heap-based buffer overflow.
    The attack must be carried out locally. The exploit has been disclosed to the public and may be used. The     identifier of the patch is 9ca499644a21ceb3f946d1c179c38a83be084490. To fix this issue, it is recommended     to deploy a patch. The code maintainer replied with [f]ixed for 2.46. (CVE-2025-11083)

  - ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly     untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted     sources are the command line and %-sequence expansion of a configuration file. (A configuration file that     provides a complete literal username is not categorized as an untrusted source.) (CVE-2025-61984)

  - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code     execution when a ProxyCommand is used. (CVE-2025-61985)

  - LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable     Network Graphics) raster image files. From version 1.6.0 to before 1.6.51, an out-of-bounds read     vulnerability exists in png_image_read_composite when processing palette images with     PNG_FLAG_OPTIMIZE_ALPHA enabled. The palette compositing code in png_init_read_transformations incorrectly     applies background compositing during premultiplication, violating the invariant component  alpha  257     required by the simplified PNG API. This issue has been patched in version 1.6.51. (CVE-2025-64720)

The remote NewStart CGSL host, running version MAIN 7.02, has openssh packages installed that are affected by multiple vulnerabilities:

  - ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code     execution when a ProxyCommand is used. (CVE-2025-61985)

  - ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly     untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted     sources are the command line and %-sequence expansion of a configuration file. (A configuration file that     provides a complete literal username is not categorized as an untrusted source.) (CVE-2025-61984)

    OpenSSH before 10.3 mishandles the authorized_keys principals option in uncommon scenarios involving a     principals list in conjunction with a Certificate Authority that makes certain use of comma     characters.(CVE-2026-35414)

    In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to     some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without
    -p (preserve mode).(CVE-2026-35385)

    In OpenSSH before 10.3, command execution can occur via shell metacharacters in a username within a     command line. This requires a scenario where the username on the command line is untrusted, and also     requires a non-default configurations of % in ssh_config.(CVE-2026-35386)

    OpenSSH before 10.3 can use unintended ECDSA algorithms. Listing of any ECDSA algorithm in     PubkeyAcceptedAlgorithms or HostbasedAcceptedAlgorithms is misinterpreted to mean all ECDSA     algorithms.(CVE-2026-35387)

    OpenSSH before 10.3 omits connection multiplexing confirmation for proxy-mode multiplexing     sessions.(CVE-2026-35388)

    Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability     affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream     project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows     an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which     will call the underlying function and continue the execution of the program without setting the related     connection variables. As the variables are not initialized to NULL the code later accesses those     uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended     workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the     vulnerability depends heavily on the compiler flag hardening configuration.(CVE-2026-3497)
