HIGH Summary
An issue was discovered in fs/f2fs/inode.c in the Linux kernel through 4.17.3. A denial of service (slab out-of-bounds read and BUG) can occur for a modified f2fs filesystem image in which FI_EXTRA_ATTR is set in an inode.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

The following security bugs were fixed : - CVE-2018-13096: A denial of service (out-of-bounds memory access and BUG) can occur upon encountering an abnormal bitmap size when mounting a crafted f2fs image (bnc#1100062). - CVE-2018-13097: There is an out-of-bounds read or a divide-by-zero error for an incorrect user_block_count in a corrupted f2fs image, leading to a denial of service (BUG) (bnc#1100061). - CVE-2018-13098: A denial of service (slab out-of-bounds read and BUG) can occur for a modified f2fs filesystem image in which FI_EXTRA_ATTR is set in an inode (bnc#1100060). - CVE-2018-13099: A denial of service (out-of-bounds memory access and BUG) can occur for a modified f2fs filesystem image in which an inline inode contains an invalid reserved blkaddr (bnc#1100059). - CVE-2018-13100: An issue was discovered in fs/f2fs/super.c which did not properly validate secs_per_zone in a corrupted f2fs image, as demonstrated by a divide-by-zero error (bnc#1100056). - CVE-2018-14613: There is an invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, because of a lack of block group item validation in check_leaf_item in fs/btrfs/tree-checker.c (bnc#1102896). - CVE-2018-14617: There is a NULL pointer dereference and panic in hfsplus_lookup() in fs/hfsplus/dir.c when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bnc#1102870). - CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack-based buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable (bnc#1107829). - CVE-2018-16276: Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges (bnc#1106095). - CVE-2018-16597: Incorrect access checking in overlayfs mounts could be used by local attackers to modify or truncate files in the underlying filesystem (bnc#1106512). - CVE-2018-17182: The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399). - CVE-2018-7480: The blkcg_init_queue function in block/blk-cgroup.c allowed local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure (bnc#1082863). - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536).
