JSON

The dtls1_reassemble_fragment function in d1_both.c in OpenSSL before
0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly
validate fragment lengths in DTLS ClientHello messages, which allows remote
attackers to execute arbitrary code or cause a denial of service (buffer
overflow and application crash) via a long non-initial fragment.

Notes

Author	Note
mdeslaur	code in lucid is different, doesn’t look vulnerable as it just discards multiple fragments. See: https://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=c713a4c04d096fca04c42a95dddec235d9390136 and http://rt.openssl.org/Ticket/Display.html?id=2230
