The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3559 advisory.

    Package        : libssh2     Version        : 1.8.0-2.1+deb10u1     CVE ID         : CVE-2019-13115 CVE-2019-17498 CVE-2020-22218     Debian Bug     : 932329 943562

    Vulnerabilities were found in libssh2, a client-side C library     implementing the SSH2 protocol, which could lead to denial of service or     remote information disclosure.

    CVE-2019-13115

        Kevin Backhouse discovered an integer overflow vulnerability in kex.c's         kex_method_diffie_hellman_group_exchange_sha256_key_exchange()         function, which could lead to an out-of-bounds read in the way         packets are read from the server.  A remote attacker who compromises         an SSH server may be able to disclose sensitive information or cause         a denial of service condition on the client system when a user         connects to the server.

    CVE-2019-17498

        Kevin Backhouse discovered that the SSH_MSG_DISCONNECT logic in         packet.c has an integer overflow in a bounds check, thereby enabling         an attacker to specify an arbitrary (out-of-bounds) offset for a         subsequent memory read.  A malicious SSH server may be able to         disclose sensitive information or cause a denial of service         condition on the client system when a user connects to the server.

    CVE-2020-22218

        An issue was discovered in function _libssh2_packet_add(), which         could allow attackers to access out of bounds memory.

    For Debian 10 buster, these problems have been fixed in version     1.8.0-2.1+deb10u1.

    We recommend that you upgrade your libssh2 packages.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has libssh2 packages installed that are affected by a vulnerability:

  - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow     in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent     memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of     service condition on the client system when a user connects to the server. (CVE-2019-17498)

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2848 advisory.

    Two issues have been discovered in libssh2, a client-side C library implementing the SSH2 protocol:
    CVE-2019-13115: kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c has an integer     overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote     attacker who compromises a SSH server may be able to disclose sensitive information or cause a denial of     service condition on the client system when a user connects to the server. CVE-2019-17498:
    SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to     specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able     to disclose sensitive information or cause a denial of service condition on the client system when a user     connects to the server. For Debian 9 stretch, these problems have been fixed in version 1.7.0-1+deb9u2. We     recommend that you upgrade your libssh2 packages.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has libssh2 packages installed that are affected by a vulnerability:

  - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow     in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent     memory read.

An update of the nmap package has been released.

The version of AOS installed on the remote host is prior to 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 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)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - 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)
