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

  - sf-pcapng.c in libpcap before 1.9.1 does not properly
    validate the PHB header length before allocating
    memory.(CVE-2019-15165)

  - rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF
    because a URL may be provided as a capture
    source.(CVE-2019-15164)

  - rpcapd/daemon.c in libpcap before 1.9.1 allows
    attackers to cause a denial of service (NULL pointer
    dereference and daemon crash) if a crypt() call
    fails.(CVE-2019-15163)

  - rpcapd/daemon.c in libpcap before 1.9.1 mishandles
    certain length values because of reuse of a variable.
    This may open up an attack vector involving extra data
    at the end of a request.(CVE-2019-15161)

  - rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows
    platforms provides details about why authentication
    failed, which might make it easier for attackers to
    enumerate valid usernames.(CVE-2019-15162)

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.");
