Name of the Vulnerable Software and Affected Versions: Bitcoin Core versions prior to 0.20.0

Description: The issue allows remote attackers to cause a denial of service, resulting in memory consumption and application crash. This is achieved via a BIP21 r parameter for a URL that has a large file.

Recommendations: For versions prior to 0.20.0, update to version 0.20.0 or later to resolve the issue. As a temporary workaround, consider restricting access to URLs with large files to minimize the risk of exploitation. Avoid using the r parameter in BIP21 URLs for large files until the issue is resolved.
