| Doc Text: |
A flaw was found in dpkg-deb, a component of the Debian package management system. This vulnerability allows a local user to trigger a Denial of Service (DoS) by providing a specially crafted zstd-compressed .deb archive. The flaw occurs because dpkg-deb does not properly validate the end of the data stream during decompression, leading to an infinite loop that consumes CPU resources. This can make the system unresponsive.
