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 update package also includes non-security fixes. See advisory for details.
