Lifecycle Timeline
4DescriptionGitHub Advisory
GuardDog is a CLI tool to identify malicious PyPI packages. Prior to 2.7.1, GuardDog's safe_extract() function does not validate decompressed file sizes when extracting ZIP archives (wheels, eggs), allowing attackers to cause denial of service through zip bombs. A malicious package can consume gigabytes of disk space from a few megabytes of compressed data. This vulnerability is fixed in 2.7.1.
AnalysisAI
GuardDog versions prior to 2.7.1 fail to validate decompressed file sizes when extracting Python package archives, enabling denial of service attacks through zip bomb payloads that can consume gigabytes of disk space from minimal compressed data. Public exploit code exists for this vulnerability, affecting users who rely on GuardDog to scan PyPI packages for malicious content. Upgrade to version 2.7.1 or later to remediate this flaw.
