  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and AVX
 registers) between processes. These registers might contain encryption keys
 when doing SSE accelerated AES enc/decryption (bsc#1087086)
- CVE-2018-5848: In the function wmi_set_ie(), the length validation code did
 not handle unsigned integer overflow properly. As a result, a large value of
 the 'ie_len' argument could have caused a buffer overflow (bnc#1097356)
- CVE-2018-1000204: Prevent infoleak caused by incorrect handling of the SG_IO
 ioctl (bsc#1096728)
- CVE-2017-13305: Prevent information disclosure vulnerability in
 encrypted-keys (bsc#1094353)
- CVE-2018-1094: The ext4_fill_super function did not always initialize the
 crc32c checksum driver, which allowed attackers to cause a denial of service
 (ext4_xattr_inode_hash NULL pointer dereference and system crash) via a crafted
 ext4 image (bsc#1087007).
- CVE-2018-1093: The ext4_valid_block_bitmap function allowed attackers to
 cause a denial of service (out-of-bounds read and system crash) via a crafted
 ext4 image because balloc.c and ialloc.c do not validate bitmap block numbers
 (bsc#1087095).
- CVE-2018-1092: The ext4_iget function mishandled the case of a root directory
 with a zero i_links_count, which allowed attackers to cause a denial of service
 (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4
 image (bsc#1087012).
- CVE-2018-1130: NULL pointer dereference in dccp_write_xmit() function that
 allowed a local user to cause a denial of service by a number of certain
 crafted system calls (bsc#1092904)
- CVE-2018-5803: Prevent error in the '_sctp_make_chunk()' function when
 handling SCTP packets length that could have been exploited to cause a kernel
 crash (bnc#1083900)
- CVE-2018-7492: Prevent NULL pointer dereference in the net/rds/rdma.c
 __rds_rdma_map() function that allowed local attackers to cause a system panic
 and a denial-of-service, related to RDS_GET_MR and RDS_GET_MR_FOR_DEST
 (bsc#1082962)

The following non-security bugs were fixed:

- Btrfs: fix unexpected balance crash due to BUG_ON (bsc#1038553).
- Fix excessive newline in /proc/*/status (bsc#1094823).
- KVM: x86: Sync back MSR_IA32_SPEC_CTRL to VCPU data structure (bsc#1096242, bsc#1096281).
- dm thin metadata: call precommit before saving the roots (bsc#1083382).
- dm thin: fix inability to discard blocks when in out-of-data-space mode (bsc#1083382).
- dm thin: fix missing out-of-data-space to write mode transition if blocks are released (bsc#1083382).
- dm thin: restore requested 'error_if_no_space' setting on OODS to WRITE transition (bsc#1083382).
- dm: fix various targets to dm_register_target after module __init resources created (bsc#1083382).
- kABI: work around BPF SSBD removal ... [Please see the references for more information on the vulnerabilities]");
