Title: w3m vulnerabilities
Summary: Several security issues were fixed in w3m.
A large number of security issues were discovered in the w3m browser. If a

exploit a variety of issues related to web browser security, including
cross-site scripting attacks, denial of service attacks, and arbitrary code
execution.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2016-8399 net: ping: check minimum size on ICMP header length
net: ping: check minimum size on ICMP header length
Prior to commit c0371da6047a ("put iov_iter into msghdr") in v3.19, there
was no check that the iovec contained enough bytes for an ICMP header,
and the read loop would walk across neighboring stack contents. Since the
iov_iter conversion, bad arguments are noticed, but the returned error is
EFAULT. Returning EINVAL is a clearer error and also solves the problem
prior to v3.19.
This was found using trinity with KASAN on v3.18:
