What's in 1.77.2

This release includes a fix for CVE-2024-24576.

Before this release, the Rust standard library did not properly escape arguments when invoking batch files (with the bat and cmd extensions) on Windows using the Command API. An attacker able to control the arguments passed to the spawned process could execute arbitrary shell commands by bypassing the escaping.

This vulnerability is CRITICAL if you are invoking batch files on Windows with untrusted arguments. No other platform or use is affected.

You can learn more about the vulnerability in the dedicated advisory.
