Name of the Vulnerable Software and Affected Versions Net::DNS versions prior to 1.56 Description An issue exists where the software allows a Denial of Service via deep DNS compression pointer chains. The Net::DNS::DomainName::decode function follows RFC 1035 compression pointers by recursing int...

CVE-2026-47180

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

CVE-2026-47180 Zeroconf: Unbounded recursion in DNS compression-pointer decoder allows LAN-local denial of service

Zeroconf is a pure Python implementation of multicast DNS service discovery. Prior to 0.149.5, DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer, and a single mDNS packet carrying chained pointers can trigger a RecursionError that escapes DNSIncoming.init, causing...

GHSA-MXWC-WH95-PW4G Trapster Community: Unauthenticated malformed DNS compression pointers crash per-packet honeypot handler

Summary trapster.libs.dns.decodelabels decodes DNS names from attacker-supplied UDP packets and recurses once per RFC 1035 compression pointer with no cycle detection and no depth bound. A single unauthenticated UDP datagram sent to the DNS honeypot drives the function past CPython's recursion...

Uncontrolled Recursion

Overview trapster is a Trapster Daemon Affected versions of this package are vulnerable to Uncontrolled Recursion through the decodelabels function. An attacker can cause the application to crash and disrupt service by sending specially crafted UDP packets containing malformed DNS compression...

CVE-2026-42304

A flaw was found in Twisted, specifically within the twisted.names module. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted TCP DNS packet containing deeply chained compression pointers. This can lead to resource exhaustion, causing the...

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'...
