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

  - libxslt through 1.1.33 allows bypass of a protection
    mechanism because callers of xsltCheckRead and
    xsltCheckWrite permit access even upon receiving a -1
    error code. xsltCheckRead can return -1 for a crafted
    URL that is not actually invalid and is subsequently
    loaded.(CVE-2019-11068)

  - In libxslt 1.1.29 and earlier, the EXSLT math.random
    function was not initialized with a random seed during
    startup, which could cause usage of this function to
    produce predictable outputs.(CVE-2015-9019)

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.");
