rardecode: DoS risk due to unrestricted RAR dictionary sizes

Quick fix

GHSA-rwvp-r38j-9rgg — github.com/nwaples/rardecode/v2: upgrade to the fixed version with the command below.

go get github.com/nwaples/rardecode/v2@v2.2.0

Details

rardecode versions <= 2.1.1 fail to restrict the dictionary size when reading large RAR dictionary sizes, which allows an attacker to provide a specially crafted RAR file and cause Denial of Service via an Out Of Memory Crash.
