This update for the Linux Kernel 3.12.74-60_64_51 fixes several issues.
The following security bugs were fixed:
- CVE-2017-1000112: Prevent a race condition in net-packet code that could
have been exploited by unprivileged users to gain root access
(bsc#1052368).
- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
in the Linux kernel 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#1038564,
bsc#1042892).
- CVE-2017-8890: The inet_csk_clone_lock function in
net/ipv4/inet_connection_sock.c in the Linux kernel 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).
