> DESCRIPTION

Kitty is a cross-platform GPU based terminal. In versions prior to 0.47.2, a local privilege escalation vulnerability exists in kitty's file transmission protocol where a child process running in the terminal can write to arbitrary files on the filesystem by exploiting a TOCTOU (Time-of-Check-Time-of-Use) race condition between symlink validation and file creation. The `os.open()` call used to create files does not use `O_NOFOLLOW`, allowing an attacker to create a symlink between the initial stat check and the actual file open, causing the write to follow the symlink to an arbitrary destination. Version 0.47.2 fixes the issue.

CWE-59 CWE-367 CWE-426

> CWE DETAILED DESCRIPTIONS

CWE-59: Improper Link Resolution Before File Access - The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. | CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition - The product checks the state of a resource before using that resource, but the resource's state can change between the check and the use in a way that invalidates the results of the check. | CWE-426: Untrusted Search Path - The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control.
