The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall interface
for bridging. This allowed a privileged user to arbitrarily write to a limited
range of kernel memory (bnc#1085107).
- CVE-2017-18221: The __munlock_pagevec function allowed local users to cause a
denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall
and munlockall system calls (bnc#1084323).
- CVE-2018-1066: Prevent NULL pointer dereference in
fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed
The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-5715: Systems with microprocessors utilizing speculative
execution and indirect branch prediction may allow unauthorized disclosure
of information to an attacker with local user access via a side-channel
analysis (bnc#1068032).
The previous fix using CPU Microcode has been complemented by building
the Linux Kernel with return trampolines aka 'retpolines'.
- CVE-2017-18079: drivers/input/serio/i8042.c allowed attackers to cause a
denial of service (NULL pointer dereference and sy
The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
This update adds mitigations for various side channel attacks against
modern CPUs that could disclose content of otherwise unreadable memory
(bnc#1068032).
- CVE-2017-5753 / 'SpectreAttack': Local attackers on systems with modern
CPUs featuring deep instruction pipelining could use attacker
controllable speculative execution over code patterns in the Linux
Kernel to leak content from otherwise not readable memory in the same
address space, allowing retrieval of passwords, cryptographic keys
and other secrets.
This problem is mit
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages. (bnc#1069702)
- CVE-2017-1000405: mm, thp: do not dirty huge pages on read fault (bnc#1069496).
- CVE-2017-16649: The usbnet_generic_cdc_bind function in drivers/net/usb/cdc_ether.c in the Linux kernel allowed local users to
The SUSE Linux Enterprise 12 SP1 LTS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bnc#1064388).
- CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacke
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive the following security fixes:
- CVE-2017-1000251: The native Bluetooth stack in the Linux Kernel was
vulnerable to a stack overflow while processing L2CAP configuration
responses, resulting in a potential remote denial-of-service vulnerability
but no remote code execution due to use of CONFIG_CC_STACKPROTECTOR.
[bnc#1057389]
The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.74 to the following security updates:
- CVE-2017-1000111: fix race condition in net-packet code that could be
exploited to cause out-of-bounds memory access (bsc#1052365).
- CVE-2017-1000112: fix race condition in net-packet code that could have been
exploited by unprivileged users to gain root access. (bsc#1052311).
The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.74 to receive
the following security fix:
- CVE-2017-7533: Bug in inotify code allowed privilege escalation (bnc#1049483).
This Linux kernel update for SUSE Linux Enterprise 12 SP1 fixes the following issues:
- A previous security update to address CVE-2017-1000364 caused unintended
side-effects in several other tools, most notably Java. These issues have
been remedied. [bsc#1045340]
The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-1000364: The default stack guard page was too small and could be 'jumped over' by userland programs using
more than one page of stack in functions and so lead to memory corruption. This update extends the stack guard page
to 1 MB (for 4k pages) and 16 MB (for 64k pages) to reduce this attack vector. This is not a kernel bugfix, but a
hardening measure against this kind of userland attack.(bsc#1039348)
The following non-security bugs were fixed:
