The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5586 advisory.

    Several vulnerabilities have been discovered in OpenSSH, an implementation of the SSH protocol suite.
    CVE-2021-41617 It was discovered that sshd failed to correctly initialise supplemental groups when     executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or     AuthorizedPrincipalsCommandUser directive has been set to run the command as a different user. Instead     these commands would inherit the groups that sshd was started with. CVE-2023-28531 Luci Stanescu reported     that a error prevented constraints being communicated to the ssh-agent when adding smartcard keys to the     agent with per-hop destination constraints, resulting in keys being added without constraints.
    CVE-2023-48795 Fabian Baeumer, Marcus Brinkmann and Joerg Schwenk discovered that the SSH protocol is     prone to a prefix truncation attack, known as the Terrapin attack. This attack allows a MITM attacker to     effect a limited break of the integrity of the early encrypted SSH transport protocol by sending extra     messages prior to the commencement of encryption, and deleting an equal number of consecutive messages     immediately after encryption starts. Details can be found at https://terrapin-attack.com/ CVE-2023-51384     It was discovered that when PKCS#11-hosted private keys were added while specifying destination     constraints, if the PKCS#11 token returned multiple keys then only the first key had the constraints     applied. CVE-2023-51385 It was discovered that if an invalid user or hostname that contained shell     metacharacters was passed to ssh, and a ProxyCommand, LocalCommand directive or match exec predicate     referenced the user or hostname via expansion tokens, then an attacker who could supply arbitrary     user/hostnames to ssh could potentially perform command injection. The situation could arise in case of     git repositories with submodules, where the repository could contain a submodule with shell characters in     its user or hostname. For the oldstable distribution (bullseye), these problems have been fixed in version     1:8.4p1-5+deb11u3. For the stable distribution (bookworm), these problems have been fixed in version     1:9.2p1-2+deb12u2. We recommend that you upgrade your openssh packages. For the detailed security status     of openssh please refer to its security tracker page at: https://security-     tracker.debian.org/tracker/openssh

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0215 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2021-41617:
      sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows     privilege escalation because supplemental groups are not initialized as expected. Helper programs for     AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group     memberships of the sshd process, if the configuration specifies running the command as a different user.

      CVE-2020-14145:
      The client side in OpenSSH 5.7 through 8.4 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). NOTE: some reports state that     8.5 and 8.6 are also affected.

The version of AOS installed on the remote host is prior to 6.1.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.1.1 advisory.

  - JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write     access to the Log4j configuration. The attacker can provide TopicBindingName and     TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result     in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2     when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of     life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the     previous versions. (CVE-2021-4104)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix     this issue by removing support for message lookup patterns and disabling JNDI functionality by default.
    (CVE-2021-45046)

  - Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI     features used in configuration, log messages, and parameters do not protect against attacker controlled     LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters     can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From     log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3,     and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to     log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.
    (CVE-2021-44228)

  - xpointer.c in libxml2 before 2.9.5 (as used in Apple iOS before 10, OS X before 10.12, tvOS before 10, and     watchOS before 3, and other products) does not forbid namespace nodes in XPointer ranges, which allows     remote attackers to execute arbitrary code or cause a denial of service (use-after-free and memory     corruption) via a crafted XML document. (CVE-2016-4658)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for     certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how     they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and     PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and     Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
    (CVE-2021-43527)

The version of AOS installed on the remote host is prior to 5.20.4. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.20.4 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw     V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. (CVE-2022-23307)

  - NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow     when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures     encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted.

    (CVE-2021-43527)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

  - It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-     default configurations. This could allows attackers with control over Thread Context Map (MDC) input data     when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for     example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input     data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some     environments and local code execution in all environments.
