CVE-2016-0704
CVSS v3.1
5.9
Média
| Vetor | 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 1.0.0 prior to 1.0.0r
OpenSSL versions 1.0.1 prior to 1.0.1m
OpenSSL versions 1.0.2 prior to 1.0.2a
Description
The issue is related to the get client master key function in the SSLv2 implementation, where an oracle protection mechanism incorrectly overwrites MASTER-KEY bytes during the use of export cipher suites. This makes it easier for remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle.
Recommendations
For OpenSSL versions prior to 0.9.8zf, update to version 0.9.8zf or later.
For OpenSSL versions 1.0.0 prior to 1.0.0r, update to version 1.0.0r or later.
For OpenSSL versions 1.0.1 prior to 1.0.1m, update to version 1.0.1m or later.
For OpenSSL versions 1.0.2 prior to 1.0.2a, update to version 1.0.2a or later.
