Doc Text:
A race condition flaw was found in Rust's std::fs::remove_dir_all function. Rust applications that use this function may be vulnerable to a race condition where an unprivileged attacker can trick the application into deleting files and directories, causing an impact on system data integrity. If the application is privileged, an attacker can possibly delete files they would not usually have access to.

Description Marian Rehak 2022-01-17 14:29:13 UTC 
The `std::fs::remove_dir_all` standard library function is vulnerable to a race condition enabling symlink following. An attacker could use this security issue to trick a privileged program into deleting files and directories the attacker couldn't otherwise access or delete.
