CVE-2026-12244

NSD (the DNS server) is affected when configured as a secondary for a zone. A primary can crash NSD by sending an AXFR containing a DNS message with a specially crafted SVCB RR whose rdata size is 65512, which causes an (uint16_t) length to overflow while allocating space for the RR wrap (total s...

CVE-2026-12244

If NSD is configured as secondary for a zone, the primary of that zone can crash NSD with an AXFR containing a DNS message with a special crafted SVCB RR with an rdata size of 65512, that let's an uint16t variable that is used to allocate space needed for the RR wrap because total size 65535,...

CVE-2026-12246

NSD version 4.14.0 introduced a bug where a specially crafted APL RR, with an adflength larger than permitted for the address family will overwrite the stack when the zone is written to disk, with a maximum of 111 attacker controlled bytes...

CVE-2026-12245

NSD from version 4.13.0 has a heap use-after-free bug in logging errors on TLS connections, causing a crash of the server process, which can be triggered trivially by sending a DNS query over a DoT connection, and closing the connection without reading the response...

Astra Linux – Vulnerability in unbound

Unbound versions up to and including 1.24.1 are vulnerable to possible domain hijack attacks. Promiscuous NS RRSets that complement positive DNS replies in the authority section can be used to trick resolvers into updating their delegation information for the zone. Typically, these RRSets are use...
