| CVE-2018-1000127 | 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. | [email protected] | 7.5 | 1.00% | 2018-03-13 | 2024-11-21 |

| CVE-2013-7291 | memcached before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (crash) via a request that triggers an "unbounded key print" during logging, related to an issue that was "quickly grepped out of the source tree," a different vulnerability than CVE-2013-0179 and CVE-2013-7290. | [email protected] | 1.8 | 0.21% | 2014-01-13 | 2026-04-29 |
| CVE-2013-7290 | The do_item_get function in items.c in memcached 1.4.4 and other versions before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (segmentation fault) via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers a buffer over-read when printing to stderr, a different vulnerability than CVE-2013-0179. | [email protected] | 1.8 | 0.21% | 2014-01-13 | 2026-04-29 |

| CVE-2013-0179 | The process_bin_delete function in memcached.c in memcached 1.4.4 and other versions before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (segmentation fault) via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers a buffer over-read when printing to stderr. | [email protected] | 1.8 | 1.34% | 2014-01-13 | 2026-04-29 |
