Descrição técnica

ESP-Protocols is a collection of protocol components for ESP-IDF. Prior to mDNS version 1.11.2, the `mdns` component follows DNS name-compression pointers recursively when parsing fully qualified domain names (FQDNs) in inbound mDNS packets without capping pointer-follow depth in `mdns_utils_read_fqdn()`. An unauthenticated attacker on the same link-local network can send a crafted packet to UDP port 5353 on an `ESP-IDF` device using `espressif/mdns` with mDNS enabled. Deep recursion exhausts the fixed-size stack of the mDNS FreeRTOS task, causing a controlled panic and reboot; persistent malicious traffic can cause a crash loop. No confidentiality or integrity impact has been demonstrated, and remote code execution is not claimed. This issue is fixed in mDNS version 1.11.2.

CVE-2026-1236067.5 ALT

—

———The hickory-dns recursor in hickory-recursor 0.25.0-alpha.3 through 0.25.2 and hickory-resolver 0.26.0-alpha.1 before 0.26.2 iterates every out-of-bailiwick NS target lacking glue in a referral without any per-query work budget. Remote attackers can serve such referrals to force A and AAAA lookups per target, amplifying traffic against remote servers or exhausting recursor resources.7h CVE-2026-1235867.5 ALT

—

———Hickory DNS 0.25.0-alpha.3 through 0.25.2 contains a query amplification vulnerability in its recursive resolver, which mishandles cyclic sibling name server referrals that lack glue records. Attackers controlling two zones whose name servers reference each other without glue records can make the recursor loop, sending many upstream queries, amplified further by zero-TTL NS records.7h CVE-2026-1235855.3 MÉD

—

———The hickory-resolver component of Hickory DNS 0.25.0 before 0.26.2 follows irrelevant CNAME records when resolving recursive queries, sending queries that are unnecessary to answer the original request. Attackers controlling DNS responses can include CNAME records in the authority or additional sections, or outside the original query name's CNAME chain, causing excess resolver queries and increased query amplification.7h CVE-2026-1235707.5 ALT

—

———The DNS wire-format message parser in hickory-proto (Hickory DNS) 0.18 before 0.26.2 preallocates record vectors sized by the untrusted ANCOUNT, NSCOUNT, and ARCOUNT header fields before reading record data. Remote attackers can send a UDP datagram, or a spoofed response to a client/resolver, with these counts set to 65535, forcing about 18MB of allocation per message.7h CVE-2026-1235667.5 ALT

—

———Sveltejs devalue before 5.9.3 contains a denial of service vulnerability that allows attackers to cause CPU amplification by supplying sparse arrays to uneval. Attackers who influence sparse values passed to uneval can force synchronous work proportional to the declared array length, blocking the event loop.7h CVE-2026-1235657.5 ALT

—

———Sveltejs devalue before 5.9.3 contains a resource exhaustion vulnerability where repeated primitive strings cause quadratic expansion in the uneval function. Attackers can supply a small crafted payload that is parsed and then passed to uneval, producing a very large serialized string that exhausts memory or CPU.7h
