kernel: Permission bypass on overlayfs during copy_up

The ovlsetattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application...

UBUNTU-CVE-2016-1575

The overlayfs implementation in the Linux kernel through 4.5.2 does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory...

USN-2858-2 linux-lts-wily vulnerability

Nathan Williams discovered that overlayfs in the Linux kernel incorrectly handled setattr operations. A local unprivileged attacker could use this to create files with administrative permission attributes and execute arbitrary code with elevated privileges...

Linux kernel 'fs/overlayfs/inode.c' local boost vulnerability

Linux kernel is an open source operating system. Linux kernel 'fs/overlayfs/inode.c' has a security vulnerability that allows local attackers to exploit the vulnerability to gain root privileges...
