F5 Networks BIG-IP : OpenSSL vulnerabilities (SOL95463126) (DROWN)
Medium Nessus Plugin ID 89945
SynopsisThe remote device is missing a vendor-supplied security patch.
DescriptionThe get_client_master_key function in s2_srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher, which allows man-in-the-middle attackers to determine the MASTER-KEY value and decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, a related issue to CVE-2016-0800.
SolutionUpgrade to one of the non-vulnerable versions listed in the F5 Solution SOL95463126.
