CVE-2019-19449

CVE-2019-19449 affects the Linux kernel (5.0.21) where mounting a crafted f2fs filesystem image can trigger a slab-out-of-bounds read in ft2fs_build_segment_manager (fs/f2fs/segment.c). The root cause is an unvalidated second argument to get_seg_entry when computing init_min_max_mtime in fs/f2fs/...

runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfslinux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory...

CVE-2019-19319

In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4xattrsetentry use-after-free in fs/ext4/xattr.c when a large oldsize value is used in a memset call, aka CID-345c0dbf3a30...

CVE-2019-19319

CVE-2019-19319 : In the Linux kernel prior to 5.2, a setxattr operation following a mount of a crafted ext4 image can trigger a slab-out-of-bounds write via ext4_xattr_set_entry use-after-free when a large old_size is used in memset in fs/ext4/xattr.c. This is an information disclosure/DoS risk p...
