Security update for the Linux Kernel (Live Patch 13 for SLE 12 SP2)
This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
The following security issue was fixed:
- CVE-2017-18075: crypto/pcrypt.c in the Linux kernel mishandled freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls (bsc#1077404).
Non security issue fixed:
- btrfs: account for pinned bytes in should_alloc_chunk (bsc#1077268)
Security update for the Linux Kernel (Live Patch 13 for SLE 12 SP2)
This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
The following security issues were fixed:
- CVE-2017-17712: The raw_sendmsg() function had a race condition that lead to uninitialized stack pointer usage. This allowed a local user to execute code and gain privileges (bsc#1073230).
- CVE-2017-16939: The XFRM dump policy implementation 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 (bsc#1069708).

The following security issues were fixed:
- CVE-2017-1000405: Problematic use of pmd_mkdirty() in the touch_pmd() function allowed users to overwrite read-only huge pages (e.g. the zero huge page and sealed shmem files) (bsc#1070307).
- CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c 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 (bsc#1069708).
This non-security issue was fixed:
- bsc#1062847: Enabl

This update for the Linux Kernel 4.4.74-92_38 fixes several issues.
The following security issues 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 (bsc#1064392)
- 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 attacker within radio range to replay

The following security bugs were fixed:
- 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-2017-12762: In drivers/isdn/i4l/isdn_net.c a user-controlled buffer was copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow (bsc#1053150).
The SUSE Linux Enterprise 12 SP2 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.
