CVE-2025-6297 found in deb/debian/dpkg@1.22.21

Important

Risk: 0.89 (Low) CVSS: 8.2

Description

It was discovered that dpkg-deb does not properly sanitize directory permissions when extracting a control member into a temporary directory, which is documented as being a safe operation even on untrusted data. This may result in leaving temporary files behind on cleanup. Given automated and repeated execution of dpkg-deb commands on adversarial .deb packages or with well compressible files, placed inside a directory with permissions not allowing removal by a non-root user, this can end up in a DoS scenario due to causing disk quota exhaustion or disk full conditions.

Affected component

The vulnerability is in pkg:deb/debian/dpkg@1.22.21, found in artifacts pkg:oci/coreutils?repository_url=registry.opencode.de/open-code/oci/coreutils&tag=latest-amd64&arch=amd64, pkg:oci/coreutils?repository_url=registry.opencode.de/open-code/oci/coreutils, pkg:oci/coreutils?repository_url=registry.opencode.de/open-code/oci/coreutils&tag=latest-arm64&arch=arm64, pkg:oci/coreutils?repository_url=registry.opencode.de/open-code/oci/coreutils&tag=latest-arm64-debug&arch=arm64, pkg:oci/coreutils?repository_url=registry.opencode.de/open-code/oci/coreutils&tag=latest-amd64-debug&arch=amd64.
