Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-0861

Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice.

CVE-2017-5715

Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system.

This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the 'retpoline' compiler feature which allows indirect branches to be isolated from speculative execution.

CVE-2017-13166

A bug in the 32-bit compatibility layer of the v4l2 ioctl handling code has been found. Memory protections ensuring user-provided buffers always point to userland memory were disabled, allowing destination addresses to be in kernel space.

CVE-2018-1000004

Luo Quan reported a race condition in the ALSA (sound) sequencer core, between multiple ioctl operations. This could lead to a deadlock or use-after-free. A local user with access to a sequencer device could use this for denial of service or possibly for privilege escalation.

CVE-2018-1000199

Andy Lutomirski discovered that the ptrace subsystem did not sufficiently validate hardware breakpoint settings. Local users can use this to cause a denial of service, or possibly for privilege escalation, on x86 (amd64 and i386) and possibly other architectures.

Additionally, some mitigations for CVE-2017-5753 are included in this release :

CVE-2017-5753

Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system.

This specific attack has been named Spectre variant 1 (bounds-check bypass) and is mitigated by identifying vulnerable code sections (array bounds checking followed by array access) and replacing the array access with the speculation-safe array_index_nospec() function.

More use sites will be added over time.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.101-1. This version also includes bug fixes from upstream versions up to and including 3.2.101. It also fixes a regression in the procfs hidepid option in the previous version (Debian bug #887106).

We recommend that you upgrade your linux packages.

The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1087: And an unprivileged KVM guest user could     use this flaw to potentially escalate their privileges     inside a guest. (bsc#1087088)

  - CVE-2018-8897: An unprivileged system user could use     incorrect set up interrupt stacks to crash the Linux     kernel resulting in DoS issue. (bsc#1087088)

  - CVE-2018-8781: The udl_fb_mmap function in     drivers/gpu/drm/udl/udl_fb.c had an integer-overflow     vulnerability allowing local users with access to the     udldrmfb driver to obtain full read and write     permissions on kernel physical pages, resulting in a     code execution in kernel space (bnc#1090643).

  - CVE-2018-10124: The kill_something_info function in     kernel/signal.c might allow local users to cause a     denial of service via an INT_MIN argument (bnc#1089752).

  - CVE-2018-10087: The kernel_wait4 function in     kernel/exit.c might allow local users to cause a denial     of service by triggering an attempted use of the
    -INT_MIN value (bnc#1089608).

  - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events     function in drivers/scsi/libsas/sas_expander.c allowed     local users to cause a denial of service (memory     consumption) via many read accesses to files in the     /sys/class/sas_phy directory, as demonstrated by the     /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file     (bnc#1084536 1087209).

  - CVE-2017-13220: An elevation of privilege vulnerability     in the Upstream kernel bluez was fixed. (bnc#1076537).
