A flaw was found in GNU Emacs. This vulnerability, a memory corruption issue, occurs when Emacs processes specially crafted SVG (Scalable Vector Graphics) CSS (Cascading Style Sheets) data. A local user could exploit this by...

An operator allowed to use the REST API can cause the Authoritative server to produce invalid HTTPS or SVCB record data, which can in turn cause LMDB database corruption, if using the LMDB backend.

A rogue primary server may cause file descriptor exhaustion and eventually a denial of service, when a PowerDNS secondary server forwards a DNS update request to it.

Incomplete escaping of LDAP queries when running with 8bit-dns enabled allows users to perform queries of internal domain subtrees.

An attacker can send a notify request that causes a new secondary domain to be added to the bind backend, but causes said backend to update its configuration to an invalid one, leading to the backend no longer able to run on the...

A rogue backend can send a crafted UDP response with a query ID off by one related to the maximum configured value, triggering an out-of-bounds write leading to a denial of service.

A rogue backend can send a crafted SVCB response to a Discovery of Designated Resolvers request, when requested via either the autoUpgrade (Lua) option to newServer or auto_upgrade (YAML) settings. DDR upgrade is not enabled by default.

A cached crafted response can cause an out-of-bounds read if custom Lua code calls getDomainListByAddress() or getAddressListByDomain() on a packet cache.

PRSD detection denial of service

A client might theoretically be able to cause a mismatch between queries sent to a backend and the received responses by sending a flood of perfectly timed queries that are routed to a TCP-only or DNS over TLS backend.
