Уязвимость функции try_read_command (memcached.c) программного средства кэширования данных memcached, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость программного средства кэширования данных memcached, связанная с переполнением целых чисел, позволяющая нарушителю вызвать отказ в обслуживании

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.

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.
