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).
Weakness
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
