Apple · Os X · CVE-2015-3774
**Name of the Vulnerable Software and Affected Versions**
Dictionary app in Apple OS X versions prior to 10.10.5
**Description**
The issue concerns the Dictionary app in Apple OS X, which does not use HTTPS, allowing man-in-the-middle attackers to obtain sensitive information by sniffing the network or spoof word definitions by modifying the client-server data stream. This is due to insufficient input validation, which can be exploited to gain access to protected information or modify the data stream between the client and server.
**Recommendations**
For versions prior to 10.10.5, update to version 10.10.5 or later to resolve the issue. As a temporary workaround, consider restricting network access to trusted sources to minimize the risk of exploitation.
