Buffer Overflow Vulnerability in OpenSSL DTLS ClientHello Message Handling

CVE-2014-0195 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

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.
