CVE-2026-101339

Name of the Vulnerable Software and Affected Versions NSD (affected versions not specified)

Description A HIP resource record that fills the RDATA near or at its limit and contains another dname RDATA field (a HIP Rendezvous server) can cause a stack overflow, allowing up to 191 bytes of attacker-controlled data to overwrite the stack. This occurs when a zone file is fed directly to NSD, such as through an operator-controlled provisioning system, rather than being written by NSD itself.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
