Scientific Linux Security Update : kernel on SL7.x x86_64

Synopsis :

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

Description :

It was found that the RFC 5961 challenge ACK rate limiting as
implemented in the Linux kernel's networking subsystem allowed an
off-path attacker to leak certain information about a given connection
by creating congestion on the global challenge ACK rate limit counter
and then measuring the changes by probing packets. An off-path
attacker could use this flaw to either terminate TCP connection and/or
inject payload into non-secured TCP connection between two endpoints
on the network. (CVE-2016-5696, Important)
