OpenSSL 1.0.1 < 1.0.1f Multiple Vulnerabilities
high Nessus Plugin ID 71857
Language:
Synopsis
The remote service is affected by multiple vulnerabilities.Description
The version of OpenSSL installed on the remote host is prior to 1.0.1f. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.1f advisory.- The ssl3_take_mac function in ssl/s3_both.c in OpenSSL 1.0.1 before 1.0.1f allows remote TLS servers to cause a denial of service (NULL pointer dereference and application crash) via a crafted Next Protocol Negotiation record in a TLS handshake. (CVE-2013-4353)
- The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client. (CVE-2013-6449)
- The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c. (CVE-2013-6450)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to OpenSSL version 1.0.1f or later.See Also
