Several vulnerabilities were discovered in memcached, a high-performance memory object caching system. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2017-9951 Daniel Shapira reported a heap-based buffer over-read in memcached 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 . CVE-2018-1000127 An integer overflow was reported in memcached, resulting in resource leaks, data corruption, deadlocks or crashes.
