DescriptionCVE.org

It was discovered that dpkg-deb (a component of dpkg, the Debian package management system) does not properly validate the end of the data stream when uncompressing a zstd-compressed .deb archive, which may result in denial of service (infinite loop spinning the CPU).

AnalysisAI

dpkg-deb fails to properly validate zstd-compressed .deb archives during decompression, allowing unauthenticated remote attackers to trigger infinite loops that exhaust CPU resources on Debian systems. This denial of service condition affects the package management system without requiring user interaction or elevated privileges. No patch is currently available for this vulnerability.

Technical ContextAI

This vulnerability (CWE-835: Loop with Unreachable Exit Condition (Infinite Loop)) exists in the denial of component. It was discovered that dpkg-deb (a component of dpkg, the Debian package management system) does not properly validate the end of the data stream when uncompressing a zstd-compressed .deb archive, which may result in denial of service (infinite loop spinning the CPU).

RemediationAI

Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.
