script_tag(name:"insight", value:"The kernel packages contain the Linux
kernel, the core of any Linux operating system. Security Fix(es): * It was found
that the packet_set_ring() function of the Linux kernel's networking
implementation did not properly validate certain block-size data. A local
attacker with CAP_NET_RAW capability could use this flaw to trigger a buffer
overflow, resulting in the crash of the system. Due to the nature of the flaw,
privilege escalation cannot be fully ruled out. (CVE-2017-7308, Important) *
Mounting a crafted EXT4 image read-only leads to an attacker controlled memory
corruption and SLAB-Out-of-Bounds reads. (CVE-2016-10208, Moderate) * A flaw was
found in the Linux kernel's implementation of seq_file where a local attacker
could manipulate memory in the put() function pointer. This could lead to memory
corruption and possible privileged escalation. (CVE-2016-7910, Moderate) * A
vulnerability was found in the Linux kernel. An unprivileged local user could
trigger oops in shash_async_export() by attempting to force the in-kernel
hashing algorithms into decrypting an empty data set. (CVE-2016-8646, Moderate)
* It was reported that with Linux kernel, earlier than version v4.10-rc8, an
application may trigger a BUG_ON in sctp_wait_for_sndbuf if the socket tx buffer
is full, a thread is waiting on it to queue more data, and meanwhile another
thread peels off the association being used by the first thread. (CVE-2017-5986,
Moderate) Red Hat would like to thank Igor Redko (Virtuozzo kernel team) for
reporting CVE-2016-8646. Additional Changes: This update also fixes several bugs
and adds various enhancements. Documentation for these changes is available from
the Technical Notes document linked to in the References section.");
