vulnerabilities :

    Amplification, CWE-406) vulnerability in the UDP
    support of the memcached server that can result in
    denial of service via network flood (traffic
    amplification of 1:50,000 has been reported by reliable
    sources). This attack appear to be exploitable via
    network connectivity to port 11211 UDP. This
    vulnerability appears to have been fixed in 1.5.6 due
    to the disabling of the UDP protocol by
    default.(CVE-2018-1000115)

  - The try_read_command function in memcached.c in
    memcached before 1.4.39 allows remote attackers to
    cause a denial of service (segmentation fault) via a
    request to add/set a key, which makes a comparison
    between signed and unsigned int and triggers a
    heap-based buffer over-read. NOTE: this vulnerability
    exists because of an incomplete fix for
    CVE-2016-8705.(CVE-2017-9951)

  - CVE-2017-9951
    Daniel Shapira reported a heap-based buffer over-read in
    memcached (resulting from an incomplete fix for
    CVE-2016-8705 ) triggered by specially crafted requests
    to add/set a key and allowing a remote attacker to cause
    a denial of service.

  - CVE-2018-1000115
    It was reported that memcached listens to UDP by
    default. A remote attacker can take advantage of it to
    use the memcached service as a DDoS amplifier.

  Default installations of memcached in Debian are not affected by
  this issue as the installation defaults to listen only on localhost.
  This update disables the UDP port by default. Listening on the UDP
  can be re-enabled in the /etc/memcached.conf (cf.
  /usr/share/doc/memcached/NEWS.Debian.gz).

  - CVE-2018-1000127
    An integer overflow was reported in memcached, resulting
    in resource leaks, data corruption, deadlocks or
    crashes."

"According to the versions of the memcached package installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - The try_read_command function in memcached.c in
    memcached before 1.4.39 allows remote attackers to
    cause a denial of service (segmentation fault) via a
    request to add/set a key, which makes a comparison
    between signed and unsigned int and triggers a
    heap-based buffer over-read. NOTE: this vulnerability
    exists because of an incomplete fix for
    CVE-2016-8705.(CVE-2017-9951)

  - Memcached version 1.5.5 contains an Insufficient
    Control of Network Message Volume (Network
    Amplification, CWE-406) vulnerability in the UDP
    support of the memcached server that can result in
    denial of service via network flood (traffic
    amplification of 1:50,000 has been reported by reliable
    sources). This attack appear to be exploitable via
    network connectivity to port 11211 UDP. This
    vulnerability appears to have been fixed in 1.5.6 due
    to the disabling of the UDP protocol by
    default.(CVE-2018-1000115)

  - memcached version prior to 1.4.37 contains an Integer
    Overflow vulnerability in items.c:item_free() that can
    result in data corruption and deadlocks due to items
    existing in hash table being reused from free list.
    This attack appear to be exploitable via network
    connectivity to the memcached service. This
    vulnerability appears to have been fixed in 1.4.37 and
    later.(CVE-2018-1000127)
