CVE-2017-3731

First published: Thu Jan 26 2017(Updated: )

If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k External References: <a href="https://www.openssl.org/news/secadv/20170126.txt">https://www.openssl.org/news/secadv/20170126.txt</a>
