Detected Windows executable files with sections that map header information to their own address space, which may lead to misuse of header information.

About the issue​

Windows executable files are mapped in memory as a sequence of allocated pages backed by its physical content. Programming language toolchains typically order these sections linearly both on disk and in memory. Starting executable file memory regions are reserved for the Portable Executable (PE) header. The operating system uses this information to correctly map the executable file in memory. Overlapping the header, its fields and tables with the rest of the executable is not recommended. Depending on the extent of the data overlap, this may lead to exposing critical security data to overwrites, tampering, and complete bypasses of vulnerability mitigations. This issue is typically reported when a software publisher uses a low quality executable packing solution.

How to resolve the issue​

  • You should deprecate the use of runtime packers or enforce digital rights management via less intrusive ways that preserve compatibility with vulnerability mitigation options.

Incidence statistics​

ReversingLabs periodically collects and analyzes the contents of popular software package repositories for threat research purposes. Analysis results are used to calculate incidence statistics for issues (policy violations) that Spectra Assure can detect in software packages.

This section is updated when new data becomes available.

Total amount of packages analyzed

  • RubyGems: 183K
  • Nuget: 644K
  • PyPi: 628K
  • NPM: 3.72M

Total detections per repository

For every repository, the chart shows the number of packages that triggered the software assurance policy. In other words, it shows how many packages in each package repository were found to have the specific issue described on this page. This information helps you understand how common the issue is across different software communities.

If a repository is absent from the chart, that means none of the packages in that repository triggered this policy during analysis, or the policy was not used during analysis.

Distribution of total detections by project popularity

For every repository, the chart shows how many of the total detections belong to the Top 100 (1-100), Top 1000 (101-1000) and Top 10 000 (1001-10 000) most downloaded projects. This information helps you understand the impact of the issue within each community, making it clearer when the issue affects the most popular projects.

If the chart shows zero values for all of the top project groups, that means all detections were in unranked projects (lower than 10 000 on the list of most downloaded projects).
