CVE-2026-101338

The NSD name server is vulnerable to a stack-based buffer overflow (CWE-121) when processing specially crafted SVCB or HTTPS resource records (RR ). If the wire format RDATA is filled to its limit, an additional ECH parameter can overwrite the stack. Furthermore, if the limit is exceeded, the bas...

CVE-2026-101337 Stack overwrite from specially formatted base64 RDATA field

When base64 data is split up in pieces, of 3 character or less, tokens were incorrectly calculated to produce 0 bytes. This enables attackers to overwrite the stack with up to 64K of attacker controlled data. Zone files which are written out by NSD itself, such as for zones for which the NSD...

CVE-2026-101337

The NSD (Name Server Daemon) is vulnerable to a stack-based buffer overflow (CWE-121 ) due to an incorrect calculation of tokens when base64 data is split into pieces of 3 characters or less. This flaw causes the system to produce 0 bytes incorrectly, allowing an attacker to overwrite the stack w...
