CVE-2016-0703
CVSS v3.1
5.9
Medium
| Vector | AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions prior to 0.9.8zf
OpenSSL versions prior to 1.0.0r
OpenSSL versions prior to 1.0.1m
OpenSSL versions prior to 1.0.2a
Description
The issue allows man-in-the-middle attackers to determine the MASTER-KEY value and decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle. This is related to an issue where the get client master key function in s2 srvr.c in the SSLv2 implementation accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH value for an arbitrary cipher.
Recommendations
For versions prior to 0.9.8zf, update to version 0.9.8zf or later.
For versions prior to 1.0.0r, update to version 1.0.0r or later.
For versions prior to 1.0.1m, update to version 1.0.1m or later.
For versions prior to 1.0.2a, update to version 1.0.2a or later.
