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

  - In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23
    and 7.4.x below 7.4.11, when PHP is processing incoming
    HTTP cookie values, the cookie names are url-decoded.
    This may lead to cookies with prefixes like __Host
    confused with cookies that decode to such prefix, thus
    leading to an attacker being able to forge cookie which
    is supposed to be secure. See also CVE-2020-8184 for
    more information.(CVE-2020-7070)

  - In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23
    and 7.4.x below 7.4.11, when AES-CCM mode is used with
    openssl_encrypt() function with 12 bytes IV, only first
    7 bytes of the IV is actually used. This can lead to
    both decreased security and incorrect encryption
    data.(CVE-2020-7069)

  - In PHP versions 7.2.x below 7.2.23, 7.3.x below 7.3.21
    and 7.4.x below 7.4.9, while processing PHAR files
    using phar extension, phar_parse_zipfile could be
    tricked into accessing freed memory, which could lead
    to a crash or information disclosure.(CVE-2020-7068)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
