CVE-2018-1000115

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.

Updated memcached packages fix security vulnerabilities:

Memcached enabled UDP by default, which could be exploited to denial of service via network flood (CVE-2018-1000115). By default this UPD is now closed.

With this release some overflow and deadlock situations get fixed too.

These are all security issues fixed in the memcached-1.6.9-2.3 package on the GA media of openSUSE Tumbleweed.
