Linux kernel XFS subsystem denial of service vulnerability

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the XFS subsystem in Linux kernel versions 4.8.2 and earlier. A local attacker can exploit this vulnerability to cause a denial of service...

PT-2016-7543

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.8.3 Description The issue allows local users to cause a denial of service, resulting in an fdatasync failure and system hang, by utilizing the vfs syscall group in the trinity program. This is related to a page...

kernel: vfs: missing detection of hardlinks in vfs_rename() on overlayfs

A flaw was found that the vfsrename function did not detect hard links on overlayfs. A local, unprivileged user could use the rename syscall on overlayfs on top of xfs to crash the system...

DEBIAN-CVE-2015-1350

The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service capability stripping via a failed invocation of a system call, as...

USN-2855-2 samba regression

USN-2855-1 fixed vulnerabilities in Samba. The upstream fix for CVE-2015-5252 introduced a regression in certain specific environments. This update fixes the problem. Original advisory details: Thilo Uttendorfer discovered that the Samba LDAP server incorrectly handled certain packets. A remote...

kernel: fs: deadlock due to incorrect usage of rename_lock

A flaw was found in the way the Linux kernel's VFS subsystem handled file system locks. A local, unprivileged user could use this flaw to trigger a deadlock in the kernel, causing a denial of service on the system...

A flaw was found in the way the Linux kernel's VFS subsystem handled file system locks. A local, unprivileged user could use this flaw to trigger a deadlock in the kernel, causing a denial of service on the system...

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 ...

samba: Uninitialized memory exposure

A flaw was found in the way Samba created responses for certain authenticated client requests when a shadow-copy VFS module was enabled. An attacker able to send an authenticated request could use this flaw to disclose limited portions of memory per each request...

Linux kernel local filesystem DoS

The 1 reallookup and 2 lookuphash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted aka SDEAD directory, which allows local users to cause a denial of service "overflow" of the UBIFS orphan area via a...

kernel: filesystem corruption by unprivileged user via directory truncation

VFS in the Linux kernel before 2.6.22.16, and 2.6.23.x before 2.6.23.14, performs tests of access mode by using the flag variable instead of the accmode variable, which might allow local users to bypass intended permissions and remove directories...
