Detected presence of software components distributed with copyleft licenses.

licenses
Problem
Software license is a legal instrument that governs the use and distribution of software source code and its binary representation. Software publishers have the freedom to choose any commonly used or purposefully written license to publish their work under. While some licenses are liberal and allow almost any kind of distribution, with or without code modification, other licenses are more restrictive and impose rules for their inclusion in other software projects. Copyleft licenses in particular impose substantial restrictions on the licensee. They typically require that any derived works, and even software code that merely interacts with copyleft code, be licensed under the same license. Since copyleft licenses are commonly applied to open source code, their inclusion requires that the entire software package becomes open sourced. For commercial applications, this is typically undesirable. Therefore, the inclusion of copyleft code is commonly avoided or even prohibited by the organization policy.Prevalence in NuGet community

Confirm that the software package includes a copyleft component.
Investigate if the software publisher provides this component under a non-copyleft license.
Consider replacing the software component with an alternative that offers a license compatible with commercial use.

Problem
Software license is a legal instrument that governs the use and distribution of software source code and its binary representation. Software publishers have the freedom to choose any commonly used or purposefully written license to publish their work under. While some licenses are liberal and allow almost any kind of distribution, with or without code modification, other licenses are more restrictive and impose rules for their inclusion in other software projects. Some software licenses place restrictions on software distribution of the code they apply to. These restrictions may extend to the services built upon the code licensed under such restrictive licenses. Some restrictive licenses explicitly state that the licensee may not provide the software to third parties as a hosted or managed service, where the service provides users with access to any substantial set of the features or functionality of the licensed software. When building commercial applications, this is typically undesirable. Therefore, the inclusion of any code that may impose limits on software distribution is commonly avoided or even prohibited by the organization policy.Prevalence in NuGet community

Confirm that the software package references a component or a dependency with a restrictive license.
Consider replacing the software component with an alternative that offers a license compatible with organization policy.
Detected Windows executable files that embed PDB files whose integrity is verified with an insecure hashing algorithm.
Causes risk: outdated toolchains detected

hardening
Problem
Program database (PDB) files are typically only used during software development. They contain private debug symbols that make it significantly easier to reverse engineer a closed-source application. In some cases, having a program database file is equivalent to having access to the source code. Presence of program databases could indicate that one or more software components have been built using a debug profile, instead of the release.Prevalence in NuGet community

Next steps
Private debug database files should not be embedded within executables, and you should remove them from the software package before releasing it.
The integrity verification of the embedded database files should not be done with insecure hashing algorithms. SHA1 and MD5 hashes should be deprecated throughout the application, and a more secure SHA256 algorithm should be used instead.
Detected digital signatures that rely on a weak digest algorithm for integrity validation.
1
signatures
Problem
Digital signatures are applied to applications, packages and documents as a cryptographically secured authenticity record. Signatures verify the origin and the integrity of the object they apply to. The integrity validation relies on the cryptographic strength of the encryption and the hash verification algorithm. If either of the two is considered weak by current standards, there is a chance the signed object could be maliciously modified, without triggering the integrity failure check.Prevalence in NuGet community

Next steps
Create signatures with strong ECC key-length of at least 224 bits, or RSA key-length of at least 2048 bits, and use SHA256 as the hashing algorithm. While encryption key-length upgrade does require you to obtain a new certificate, the hashing algorithm can freely be selected during signing.
With Microsoft SignTool, you can specify the hashing algorithm using the /fd SHA256 parameter.
Problem
Debug databases are typically only used during software development. On Windows, they are usually files embedded into the executable (PDB), while on Linux, they're contained inside special executable sections. The databases contain private debug symbols that make it significantly easier to reverse-engineer a closed-source application. In some cases, having a debug database is equivalent to having access to the source code. Presence of debug databases could indicate that one or more software components have been built using a debug profile, instead of the release. Private debug databases can be embedded into software components by programming language tools.Prevalence in NuGet community
