02 Apr 2018 — The ext4_xattr_check_entries function in fs/ext4/xattr.c in the Linux kernel through 4.15.15 does not properly validate xattr sizes, which causes misinterpretation of a size as an error code, and consequently allows attackers to cause a denial of service (get_acl NULL pointer dereference and system crash) via a crafted ext4 image. La función ext4_xattr_check_entries en fs/ext4/xattr.c en el kernel de Linux hasta la versión 4.15.15 no valida correctamente los tamaños de xattr, lo que provoca una malinterpret... • http://openwall.com/lists/oss-security/2018/03/29/1 • CWE-476: NULL Pointer Dereference •
