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

  - An out-of-bounds read in dns_validate_dns_response in
    dns.c was discovered in HAProxy through 1.8.14. Due to
    a missing check when validating DNS responses, remote
    attackers might be able read the 16 bytes corresponding
    to an AAAA record from the non-initialized part of the
    buffer, possibly accessing anything that was left on
    the stack, or even past the end of the 8193-byte
    buffer, depending on the value of
    accepted_payload_size.(CVE-2018-20102)

  - An issue was discovered in dns.c in HAProxy through
    1.8.14. In the case of a compressed pointer, a crafted
    packet can trigger infinite recursion by making the
    pointer point to itself, or create a long chain of
    valid pointers resulting in stack
    exhaustion.(CVE-2018-20103)

  - An out-of-bounds read issue was discovered in the
    HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x
    through 1.9.0 which can result in a crash. The
    processing of the PRIORITY flag in a HEADERS frame
    requires 5 extra bytes, and while these bytes are
    skipped, the total frame length was not re-checked to
    make sure they were present in the
    frame.(CVE-2018-20615)

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.");
