CentOS Errata and Security Advisory CESA-2017:0286
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.
Security Fix(es):
An integer underflow leading to an out of bounds read flaw was found in OpenSSL. A remote attacker could possibly use this flaw to crash a 32-bit TLS/SSL server or client using OpenSSL if it used the RC4-MD5 cipher suite. (CVE-2017-3731)
A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections form other clients. (CVE-2016-8610)
