"According to the versions of the perl packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerabilities :

  - An issue was discovered in Perl 5.18 through 5.26. A
    crafted regular expression can cause a heap-based
    buffer overflow, with control over the bytes
    written.(CVE-2018-6797)

  - An issue was discovered in Perl 5.22 through 5.26.
    Matching a crafted locale dependent regular expression
    can cause a heap-based buffer over-read and potentially
    information disclosure.(CVE-2018-6798)

  - Heap-based buffer overflow in the pack function in Perl
    before 5.26.2 allows context-dependent attackers to
    execute arbitrary code via a large item
    count.(CVE-2018-6913)

  - Perl before 5.26.3 and 5.28.0 before 5.28.1 has a
    buffer overflow via a crafted regular expression that
    triggers invalid write operations.(CVE-2018-18312)

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.");
