DescriptionNVD

malcontent is software for discovering supply-chain compromises through context, differential analysis, and YARA. Prior to version 1.21.0, malcontent would remove nested archives which failed to extract which could potentially leave malicious content. A better approach is to preserve these archives so that malcontent can attempt a best-effort scan of the archive bytes. Version 1.21.0 fixes the issue.

AnalysisAI

Malcontent versions before 1.21.0 fail to preserve nested archives that cannot be extracted, potentially allowing malicious content to evade detection during supply-chain compromise analysis. An attacker could exploit this by embedding malicious payloads in problematic nested archives that the tool would discard without scanning. …
