The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2019:3707 advisory.

    D-Bus is a system for sending messages between applications. It is used both for the system-wide message     bus service, and as a per-user-login-session messaging facility.

    Security Fix(es):

    * dbus: DBusServer DBUS_COOKIE_SHA1 authentication bypass (CVE-2019-12749)

The version of dbus installed on the remote host is prior to 1.10.24-7. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1870 advisory.

    A flaw was found in dbus. The implementation of DBUS_COOKIE_SHA1 is susceptible to a symbolic link attack.
    A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink     to cause the DBusServer to read and write in unintended locations resulting in an authentication bypass.
    The highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2019-12749)

    An uncontrolled resource consumption vulnerability was discovered in D-Bus. The DBusServer leaks file     descriptors when a message exceeds the per-message file descriptor limit. This flaw allows a local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket, to make     the system service reach its file descriptor limit, denying service to subsequent D-Bus clients. As a     result, the system may become unusable for other users, and some services may stop working. The highest     threat from this vulnerability is to system availability. (CVE-2020-12049)

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-2022:0097 advisory.

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

    CVE-2019-12749:
    dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical     Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of     symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only     affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own     home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to     read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a     cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent     client connection came from an attacker-chosen uid, allowing authentication bypass.

    CVE-2020-12049:
    An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients.

The version of AHV installed on the remote host is prior to 20201105.1021. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20201105.1021 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are     affected are 5.6.46 and prior, 5.7.28 and prior and 8.0.18 and prior. Difficult to exploit vulnerability     allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of MySQL Client. (CVE-2020-2574)

  - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are     affected are 5.6.47 and prior, 5.7.27 and prior and 8.0.17 and prior. Difficult to exploit vulnerability     allows low privileged attacker with network access via multiple protocols to compromise MySQL Client.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of MySQL Client. (CVE-2020-2752)

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

The remote NewStart CGSL host, running version MAIN 6.06, has dbus packages installed that are affected by multiple vulnerabilities:

  - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical     Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of     symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only     affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own     home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to     read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a     cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent     client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)

  - libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other     products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS     environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications     that do not cleanse environment variables, not in libdbus itself: we do not support use of libdbus in     setuid binaries that do not sanitize their environment before their first call into libdbus.
    (CVE-2012-3524)

  - Unspecified vulnerability in the match_rule_equal function in bus/signals.c in D-Bus before 1.0.2 allows     local applications to remove match rules for other applications and cause a denial of service (lost     process messages). (CVE-2006-6107)

  - dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow     directives in the security policy only for fully qualified method calls, which allows local users to     bypass intended access restrictions via a method call with a NULL interface. (CVE-2008-0595)

  - The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before     1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature     via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834. (CVE-2009-1189)
