-Fix buffer overflow in helper.c with large CLIDs. CVE-2026-4892
-
-Bug reported bt Royce M <royce@xchglabs.com>
-
-Location: helper.c:265-270
-DHCPv6 CLIDs can be up to 65535 bytes. When --dhcp-script is configured,
-the helper hex-encodes raw CLID bytes via sprintf("%.2x") into daemon->packet (5131 bytes).
-A 1000-byte CLID writes ~3000 bytes. The helper process retains root privileges.
-
-Note: log6_packet() correctly caps CLID to 100 bytes for logging, but the helper code path was missed.

-
-Bug report from Royce M <royce@xchglabs.com>

-length (~23 bytes) instead of the packet length to check_source().

-Fix buffer overflow vulnerability in extract_addresses() CVE-2026-5172
-
-Thanks to Hugo Martinez Ray for spotting this.
-
-The value of rdlen for an RR can be a lie, allowing the
-call to extract_name() at rfc1025.c:952 to advance the value of p1
-past the calculated end of the record. The makes the calculation
-of bytes remaining in the RR underflow to a huge number and results
-in a massive heap OOB read and certain crash.
