Scientific Linux Security Update : kernel on SL6.x i386/x86_64

High Nessus Plugin ID 97376

Synopsis

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

Description

Security Fix(es) :

- A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
(CVE-2017-6074, Important)

Solution

Update the affected packages.
