This update for the Linux Kernel 3.12.74-60_64_60 fixes several issues.
The following security bugs were fixed:
- CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not
consider the case of a NULL payload in conjunction with a nonzero length
value, which allowed local users to cause a denial of service (NULL
pointer dereference and OOPS) via a crafted add_key or keyctl system
call (bsc#1045327).
- CVE-2017-1000112: Updated patch for this issue to be in sync with the
other livepatches. Description of the issue: Prevent race condition in
net-packet code that could have been exploited by unprivileged users to
gain root access (bsc#1052368, bsc#1052311).
- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
was too late in checking whether an overwrite of an skb data structure
may occur, which allowed local users to cause a denial of service
(system crash) via crafted system calls (bsc#1042892).
- CVE-2017-8890: The inet_csk_clone_lock function in
net/ipv4/inet_connection_sock.c allowed attackers to cause a denial of
service (double free) or possibly have unspecified other impact by
leveraging use of the accept system call (bsc#1038564).
