The remote SUSE host is missing one or more security updates.
The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.126 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2018-1091: In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service (bnc#1087231). - CVE-2018-7740: The resv_map_release function in mm/hugetlb.c allowed local users to cause a denial of service (BUG) via a crafted application that made mmap system calls and has a large pgoff argument to the remap_file_pages system call (bnc#1084353). - CVE-2018-8043: The unimac_mdio_probe function in drivers/net/phy/mdio-bcm-unimac.c did not validate certain resource availability, which allowed local users to cause a denial of service (NULL pointer dereference) (bnc#1084829). - CVE-2017-18257: The __get_data_block function in fs/f2fs/data.c allowed local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl. (bnc#1088241) - CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious NCPFS servers to crash the kernel or execute code (bnc#1086162). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
