Affected: Maven: io.netty:netty-codec-http

### Description ### [GHSA-5mcr-gq6c-3hq2](https://github.com/netty/netty/security/advisories/GHSA-5mcr-gq6c-3hq2) (CVE-2021-21290) contains an insufficient fix for the vulnerability identified.

### Impact ###

When netty's multipart decoders are used local information disclosure can occur via the local system temporary directory if temporary storing uploads on the disk is enabled.

This only impacts applications running on Java version 6 and lower. Additionally, this vulnerability impacts code running on Unix-like systems, and very old versions of Mac OSX and Windows as they all share the system temporary directory between all users.

### Vulnerability Details ###

To fix the vulnerability the code was changed to the following:

```java @SuppressJava6Requirement(reason = "Guarded by version check") public static File createTempFile(String prefix, String suffix, File directory) throws IOException { if (javaVersion() >= 7) { if (directory == null) { return Files.createTempFile(prefix, suffix).toFile(); } return Files.createTempFile(directory.toPath(), prefix, suffix).toFile(); } if (directory == null) { return File.createTempFile(prefix, suffix); } File file = File.createTempFile(prefix, suffix, directory); // Try to adjust the perms, if this fails there is not much else we can do... file.setReadable(false, false); file.setReadable(true, true…
