COMPLETE Summary
The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows 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.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Forced Integer Overflow This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.

The following security bugs were fixed : - CVE-2018-3639: Information leaks using 'Memory Disambiguation' feature in modern CPUs were mitigated, aka 'Spectre Variant 4' (bnc#1087082). A new boot commandline option was introduced, 'spec_store_bypass_disable', which can have following values : - auto: Kernel detects whether your CPU model contains an implementation of Speculative Store Bypass and picks the most appropriate mitigation. - on: disable Speculative Store Bypass - off: enable Speculative Store Bypass - prctl: Control Speculative Store Bypass per thread via prctl. Speculative Store Bypass is enabled for a process by default. The state of the control is inherited on fork. - seccomp: Same as 'prctl' above, but all seccomp threads will disable SSB unless they explicitly opt out. The default is 'seccomp', meaning programs need explicit opt-in into the mitigation. Status can be queried via the /sys/devices/system/cpu/vulnerabilities/spec_store_bypas s file, containing : - 'Vulnerable' - 'Mitigation: Speculative Store Bypass disabled' - 'Mitigation: Speculative Store Bypass disabled via prctl' - 'Mitigation: Speculative Store Bypass disabled via prctl and seccomp' - 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-2018-1130: Linux kernel was vulnerable to a NULL pointer dereference in dccp_write_xmit() function in net/dccp/output.c in that allowed a local user to cause a denial of service by a number of certain crafted system calls (bnc#1092904). - CVE-2018-5803: An error in the _sctp_make_chunk() function when handling SCTP, packet length could have been exploited by a malicious local user to cause a kernel crash and a DoS. (bnc#1083900). - CVE-2018-1065: The netfilter subsystem mishandled the case of a rule blob that contains a jump but lacks a user-defined chain, which allowed local users to cause a denial of service (NULL pointer dereference) by leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability, related to arpt_do_table in net/ipv4/netfilter/arp_tables.c, ipt_do_table in net/ipv4/netfilter/ip_tables.c, and ip6t_do_table in net/ipv6/netfilter/ip6_tables.c (bnc#1083650). - CVE-2018-7492: A NULL pointer dereference was found 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 (bnc#1082962). - 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 have allowed 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 have allowed local users to cause a denial of service by triggering an attempted use of the -INT_MIN value (bnc#1089608). - 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). - CVE-2018-1000199: A bug in x86 debug register handling of ptrace() could lead to memory corruption, possibly a denial of service or privilege escalation (bsc#1089895).

vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that an integer overflow existed in the perf subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-18255) Wei Fang discovered an integer overflow in the F2FS filesystem implementation in the Linux kernel. A local attacker could use this to cause a denial of service. (CVE-2017-18257) It was discovered that an information leak existed in the generic SCSI driver in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2018-1000204) It was discovered that the wait4() system call in the Linux kernel did not properly validate its arguments in some situations. A local attacker could possibly use this to cause a denial of service. (CVE-2018-10087) It was discovered that the kill() system call implementation in the Linux kernel did not properly validate its arguments in some situations. A local attacker could possibly use this to cause a denial of service. (CVE-2018-10124) Julian Stecklina and Thomas Prescher discovered that FPU register states (such as MMX, SSE, and AVX registers) which are lazily restored are potentially vulnerable to a side channel attack. A local attacker could use this to expose sensitive information. (CVE-2018-3665) Jakub Jirasek discovered that multiple use-after-errors existed in the USB/IP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5814) It was discovered that an information leak vulnerability existed in the floppy driver in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).

A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391)Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.(CVE-2014-3184)The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows 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.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations.

A local attacker could, in extremely rare cases, use this flaw to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-4608)It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory.(CVE-2014-3534)A use-after-free flaw was found in the Linux kernel's file system encryption implementation. A local user could revoke keyring keys being used for ext4, f2fs, or ubifs encryption, causing a denial of service on the system.(CVE-2017-7374)The usbip_recv_xbuff function in drivers/usb/usbip/usbip_common.c in the Linux kernel before 4.5.3 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted length value in a USB/IP packet.(CVE-2016-3955)A flaw was found in the patches used to fix the 'dirtycow' vulnerability (CVE-2016-5195).
