Integer overflow in Dragonfly's Count-Min Sketch implementation prior to v1.40.0 allows unauthenticated remote clients to corrupt adjacent heap memory, partially disclose heap contents, and crash the server. The flaw exists in src/core/cms.cc: CMS.INITBYDIM and CMS.INITBYPROB accept width/depth parameters whose product with sizeof(int64_t) overflows size_t, causing the allocator to receive a truncated length and produce an undersized buffer; CMS.INCRBY and CMS.QUERY then operate with the original large dimensions, writing and reading past the end of that buffer. No public exploit code has been identified at time of analysis, but the CVSS 4.0 vector confirms unauthenticated network exploitation with no preconditions, rating this 8.8.
Remote denial of service in DragonflyDB before 1.39.0 lets an unauthenticated attacker crash the entire server with a single ~24-byte RESTORE command carrying a malformed listpack payload, triggering an out-of-bounds read (SIGSEGV). Because Dragonfly ships with no authentication enabled by default and RESTORE is an ordinary keyspace command, any client that can reach the port can repeatedly kill the process. No CISA KEV listing exists, but the fixing pull request publishes the exact crash payloads as regression tests, so working trigger data is effectively public.
RESP protocol injection in Dragonfly's EvalSerializer allows an authenticated low-privilege user to embed raw CRLF sequences inside Lua redis.error_reply() and redis.status_reply() return values, causing response stream desynchronization for connection-pool clients. All Dragonfly releases prior to 1.39.9 are affected; the vulnerability is confirmed fixed in 1.39.9 per GitHub security advisory GHSA-h77h-c6hc-qc9h. No public exploit has been identified at time of analysis, and exploitation requires authenticated access plus a connection-pooling client architecture, substantially limiting real-world risk.
DragonflyDB Dragonfly through 1.28.2 (fixed in 1.29.0) allows authenticated users to cause a denial of service (daemon crash) via a Lua library command that references a large negative integer. Rated low severity (CVSS 3.3), this vulnerability is low attack complexity. Public exploit code available.
DragonflyDB Dragonfly before 1.27.0 allows authenticated users to cause a denial of service (daemon crash) via a crafted Redis command. Rated low severity (CVSS 3.3), this vulnerability is low attack complexity. Public exploit code available.
