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

  - do_core_note in readelf.c in libmagic.a in file 5.35
    allows remote attackers to cause a denial of service
    (stack corruption and application crash) or possibly
    have unspecified other impact.(CVE-2019-8907)

  - do_core_note in readelf.c in libmagic.a in file 5.35
    has an out-of-bounds read because memcpy is
    misused.(CVE-2019-8906)

  - do_core_note in readelf.c in libmagic.a in file 5.35
    has a stack-based buffer over-read, related to
    file_printable, a different vulnerability than
    CVE-2018-10360.(CVE-2019-8905)

  - do_bid_note in readelf.c in libmagic.a in file 5.35 has
    a stack-based buffer over-read, related to file_printf
    and file_vprintf.(CVE-2019-8904)

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.");
