GHSA-5v95-j4rr-6f3c: rdiffweb's unlimited username field length can lead to DoS

rdiffweb prior to 2.4.8 is vulnerable to a potential Dos attack via an unlimited length “username” field. This can result in excess memory consumption, or memory corruption, leading to a Denial of Service (DoS). This issue is patched in version 2.4.8. There are no known workarounds.
