Double-free vulnerability in the FTP-kerberos code in cURL 7.52.0 to 7.65.3.(CVE-2019-5481)

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1792 advisory.

    The curl packages provide the libcurl library and the curl utility for downloading files from servers     using various protocols, including HTTP, FTP, and LDAP.

    Security Fix(es):

    * curl: double free due to subsequent call of realloc() (CVE-2019-5481)

    * curl: heap buffer overflow in function tftp_receive_packet() (CVE-2019-5482)

    * curl: TFTP receive heap buffer overflow in tftp_receive_packet() function (CVE-2019-5436)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

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.
