  script_tag(name:"insight", value:"An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root to inspect the kernel stack of an arbitrary task.(CVE-2018-17972)

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.(CVE-2018-10883)

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bounds write and a denial of service or unspecified other impact is possible by mounting and operating a crafted ext4 filesystem image.(CVE-2018-10878)

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact may occur by renaming a file in a crafted ext4 filesystem image.(CVE-2018-10879)

A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image.(CVE-2018-10881)

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)

An issue was discovered in the XFS filesystem in fs/xfs/xfs_icache.c in the Linux kernel. There is a NULL pointer dereference leading to a system panic in lookup_slow() on a NULL inode->i_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)

In the Linux kernel before 4.17, 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 mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.(CVE-2018-18690)");
