A directory traversal (or path traversal) attack exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing "traverse to parent directory" are passed through to the operating system's file system API. An affected application can be exploited to gain unauthorized access to the file ...
A fault-tolerant, parallel POSIX file system, with block (VMs) and object (S3) interfaces, and advanced enterprise features like multi-tenancy, strong authentication, encryption. Split-brain safe fault-tolerance is achieved through Paxos-based leader election and erasure coding. RozoFS: Rozo Systems GNU GPL v2: Linux
There are various User Mode File System (FUSE)–based file systems for Unix-like operating systems (for example, Linux) that can be used to mount an S3 bucket as a file system. The semantics of the Amazon S3 file system are not that of a POSIX file system, so the file system may not behave entirely as expected. [15]
Squashfs is a compressed read-only file system for Linux. Squashfs compresses files, inodes and directories, and supports block sizes from 4 KiB up to 1 MiB for greater compression. Several compression algorithms are supported. Squashfs is also the name of free software, licensed under the GPL, for accessing Squashfs filesystems.
The metadata server cluster can expand or contract, and it can rebalance file system metadata ranks dynamically to distribute data evenly among cluster hosts. This ensures high performance and prevents heavy loads on specific hosts within the cluster. Clients mount the POSIX-compatible file system using a Linux kernel client.
In computing, mount is a command in various operating systems. Before a user can access a file on a Unix-like machine, the file system on the device [1] which contains the file needs to be mounted with the mount command. Frequently mount is used for SD card, USB storage, DVD and other removable storage devices.
Linux also supports mandatory locking through the special -o mand parameter for file system mounting , but this is rarely used. Some Unix-like operating systems prevent attempts to open the executable file of a running program for writing; this is a third form of locking, separate from those provided by fcntl and flock.
Any function that can be used to compose and run a shell command is a potential vehicle for launching a shell injection attack. Among these are system(), StartProcess(), and System.Diagnostics.Process.Start(). Client-server systems such as web browser interaction with web servers are potentially vulnerable to shell injection.
