The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6372-1 advisory.

    It was discovered that DBus incorrectly handled certain invalid messages. A local attacker could possibly     use this issue to cause DBus to crash, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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

  - D-Bus before 1.15.6 sometimes allows unprivileged users to crash dbus-daemon. If a privileged user with     control over the dbus-daemon is using the org.freedesktop.DBus.Monitoring interface to monitor message bus     traffic, then an unprivileged user with the ability to connect to the same dbus-daemon can cause a dbus-     daemon crash under some circumstances via an unreplyable message. When done on the well-known system bus,     this is a denial-of-service vulnerability. The fixed versions are 1.12.28, 1.14.8, and 1.15.6.
    (CVE-2023-34969)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update of the dbus package has been released.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2023:0171 advisory.

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

      CVE-2023-34969:

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.1011 advisory.

  - Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11,     5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server     for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J     through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using     a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to     recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown     vectors. (CVE-2008-5161)

  - The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path,     leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in     /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this issue exists because of an     incomplete fix for CVE-2016-10009. (CVE-2023-38408)

  - A NULL pointer dereference was found In libssh during re-keying with algorithm guessing. This issue may     allow an authenticated client to cause a denial of service. (CVE-2023-1667)

  - A vulnerability was found in libssh, where the authentication check of the connecting client can be     bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen     if there is insufficient memory or the memory usage is limited. The problem is caused by the return value     `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call     `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the     cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
    (CVE-2023-2283)

  - Every `named` instance configured to run as a recursive resolver maintains a cache database holding the     responses to the queries it has recently sent to authoritative servers. The size limit for that cache     database can be configured using the `max-cache-size` statement in the configuration file; it defaults to     90% of the total amount of memory available on the host. When the size of the cache reaches 7/8 of the     configured limit, a cache-cleaning algorithm starts to remove expired and/or least-recently used RRsets     from the cache, to keep memory use below the configured limit. It has been discovered that the     effectiveness of the cache-cleaning algorithm used in `named` can be severely diminished by querying the     resolver for specific RRsets in a certain order, effectively allowing the configured `max-cache-size`     limit to be significantly exceeded. This issue affects BIND 9 versions 9.11.0 through 9.16.41, 9.18.0     through 9.18.15, 9.19.0 through 9.19.13, 9.11.3-S1 through 9.16.41-S1, and 9.18.11-S1 through 9.18.15-S1.
