Synopsis: Important: kernel security and bug fix update
Advisory ID: SLSA-2016:1633-1
Issue Date: 2016-08-18
CVE Numbers: CVE-2016-5696
--

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)
