CVE-2021-30454

Name of the Vulnerable Software and Affected Versions outer cgi crate versions prior to 0.2.1

Description An issue in the outer cgi crate allows a user-provided Read instance to receive an uninitialized memory buffer from KeyValueReader. This can cause the Read instance to read uninitialized memory, leading to undefined behavior and miscompilations.

Recommendations For outer cgi crate versions prior to 0.2.1, update to version 0.2.1 or later to fix the issue by ensuring buffers are zero-initialized before being passed to the Read instance.
