Description
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.SUSE information

Note from the SUSE Security Team
According to our research, openssl before 0.9.8o is not affected by this overflow problem. The DTLS fragment reassembly was rewritten for 0.9.8o and older versions used different methods. So openssl 0.9.8j as used by SUSE Linux Enterprise 11 and older versions are not affected. Please also not that this problem only affects the Datagram TLS (over UDP) not the regular TLS over TCP which is more common.
