"According to the version of the gd package installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerability :

  - 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)

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.");
