Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)
