Description:
* SECURITY UPDATE: excessive memory use buffering DTLS records
- debian/patches/openssl-1.1.1-cve-2026-54874.patch: copy only the record's
own on-wire bytes into the queue entry in dtls1_buffer_record(), and copy
them back into the live read buffer in dtls1_copy_record(), instead of
handing the whole ~16.7KB read buffer to the queue and allocating a fresh
one, so a peer sending a stream of tiny next-epoch records can no longer
pin ~1.7MB of heap per connection; also lower the cap on the next-epoch
(unprocessed_rcds) queue from 100 records to 16, which the same patch
passes to dtls1_buffer_record() as an argument so that the other two
queues keep the 100-record limit.
