HIGH Summary
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 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.

A local user with access to a floppy drive device can take advantage of this flaw to discover the location kernel code and data. CVE-2018-9363 It was discovered that the Bluetooth HIDP implementation did not correctly check the length of received report messages. A paired HIDP device could use this to cause a buffer overflow, leading to denial of service (memory corruption or crash) or potentially remote code execution. CVE-2018-9516 It was discovered that the HID events interface in debugfs did not correctly limit the length of copies to user buffers. A local user with access to these files could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, by default debugfs is only accessible by the root user. CVE-2018-10902 It was discovered that the rawmidi kernel driver does not protect against concurrent access which leads to a double-realloc (double free) flaw. A local attacker can take advantage of this issue for privilege escalation. CVE-2018-10938 Yves Younan from Cisco reported that the Cipso IPv4 module did not correctly check the length of IPv4 options.

CVE-2018-15594 Nadav Amit reported that some indirect function calls used in paravirtualised guests were vulnerable to Spectre variant 2. A local user may be able to use this to read sensitive information from the kernel. CVE-2018-16276 Jann Horn discovered that the yurex driver did not correctly limit the length of copies to user buffers. A local user with access to a yurex device node could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2018-16658 It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_DRIVE_STATUS ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash). CVE-2018-17182 Jann Horn discovered that the vmacache_flush_all function mishandles sequence number overflows. A local user can take advantage of this flaw to trigger a use-after-free, causing a denial of service (crash or memory corruption) or privilege escalation.

There is a NULL pointer dereference leading to a system panic in lookup_slow() on a NULL inode-i1/4zi_ops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during an allocation.(CVE-2018-13093) - An issue was discovered in the XFS filesystem in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel. A NULL pointer dereference may occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. This can lead to a system crash and a denial of service.(CVE-2018-13094) - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is writable by a user who is not a member of this group. This can lead to excessive permissions granted in case when they should not.(CVE-2018-13405) - 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.

(bnc#1113769). CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025). CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). CVE-2018-9516: In hid_debug_events_read of drivers/hid/hid-debug.c, there is a possible out of bounds write due to a missing bounds check.
