CVE-2026-80213
An issue was discovered in the resolv gem before 0.7.2 for Ruby. Resolv::DNS::MessageEncoder wrote a DNS label's length into a single octet without checking its range. A label longer than 255 octets had its length stored modulo 256 but the label data was written unchanged, and thus the bytes on t...
CVE-2026-80213
CVE-2026-80213 affects the resolv gem (before 0.7.2 ) for Ruby. The vulnerability resides in Resolv::DNS::MessageEncoder , which wrote a DNS label's length into a single octet without range validation. Labels longer than 255 octets had their length stored modulo 256 while the label data was writt...

CVE-2026-64194
Net::DNS versions through 1.55 for Perl allow Denial of Service via deep DNS compression pointer chains. Net::DNS::DomainName::decode follows RFC 1035 compression pointers by recursing into itself with no depth limit. It is possible to construct a name which saturates the call stack at least with...
CVE-2026-47180
CVE-2026-47180 affects the Zeroconf Python library. The vulnerability stems from DNSIncoming._decode_labels_at_offset recursing for each DNS-name compression pointer; a crafted mDNS packet with ~1500 chained pointers can cause unbounded recursion, escaping DNSIncoming.init and triggering sustaine...
PYSEC-2026-3436 zeroconf has unbounded recursion in DNS compression-pointer decoder that allows LAN-local denial of service
Impact DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer RFC 1035 §4.1.4. Pointer cycles and label counts were capped, but the chain length of unique forward pointers was not. A single 3 kB mDNS packet carrying 1500 chained pointers drives the recursion past CPython'...
UBUNTU-CVE-2026-14461
mtr is vulnerable to Out-of-bound read vulnerability in ipinfolookup function. An attacker who can influence the TXT response used for AS lookups can trigger this bug by returning a DNS response that is larger than 512 bytes and uses a crafted compression pointer in the answer NAME...
CVE-2026-14461
The CVE-2026-14461 entry affects mtr up to version 0.96, where ipinfo_lookup() performs DNS AS lookups and can be triggered by a TXT response larger than 512 bytes with a crafted compression pointer, causing an out-of-bounds read. The function uses the response length as the end-of-message bounda...

CVE-2020-25767
CVE-2020-25767 affects HCC Embedded InterNiche/NicheStack (IPv4) prior to 4.3. The root cause is in the dnc_copy_in DNS domain name parser, which fails to validate that compression pointers stay within packet bounds, enabling an out-of-bounds read and potential DoS via crafted DNS data. Affected ...
