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

  - When using the gdImageCreateFromXbm() function in the
    GD Graphics Library (aka LibGD) 2.2.5, as used in the
    PHP GD extension in PHP versions 7.1.x below 7.1.30,
    7.2.x below 7.2.19 and 7.3.x below 7.3.6, it is
    possible to supply data that will cause the function to
    use the value of uninitialized variable. This may lead
    to disclosing contents of the stack that has been left
    there by previous code.(CVE-2019-11038)

  - In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14
    and 8.0.0, when validating URL with functions like
    filter_var($url, FILTER_VALIDATE_URL), PHP will accept
    an URL with invalid password as valid URL. This may
    lead to functions that rely on URL being valid to
    mis-parse the URL and produce wrong data as components
    of the URL.(CVE-2020-7071)

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.");
