Kernel: fs: umount denial of service

The doumount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAPSYSADMIN capability for doremountsb calls that change the root filesystem to read-only, which allows local users to cause a denial of service loss of writability by making certain unshare system calls...

DEBIAN-CVE-2017-9059

The NFSv4 implementation in the Linux kernel through 4.11.1 allows local users to cause a denial of service resource consumption by leveraging improper channel callback shutdown when unmounting an NFSv4 filesystem, aka a "module reference and kernel daemon" leak...

DEBIAN-CVE-2014-9717

fs/namespace.c in the Linux kernel before 4.0.2 processes MNTDETACH umount2 system calls without verifying that the MNTLOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user...

UBUNTU-CVE-2015-4178

The fspin implementation in the Linux kernel before 4.0.5 does not ensure the internal consistency of a certain list data structure, which allows local users to cause a denial of service system crash by leveraging user-namespace root access for an MNTDETACH umount2 system call, related to...

mod_jk: information leak due to incorrect JkMount/JkUnmount directives processing

It was discovered that a JkUnmount rule for a subtree of a previous JkMount rule could be ignored. This could allow a remote attacker to potentially access a private artifact in a tree that would otherwise not be accessible to them...

kernel: vfs: refcount issues during unmount on symlink

A flaw was found in the way the Linux kernel's VFS subsystem handled reference counting when performing unmount operations on symbolic links. A local, unprivileged user could use this flaw to exhaust all available memory on the system or, potentially, trigger a use-after-free error, resulting in ...
