Detailsinfo

A vulnerability classified as problematic was found in Debian dpkg (the affected version unknown). Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a temp file vulnerability. The CWE definition for the vulnerability is CWE-377. Creating and using insecure temporary files can leave application and system data vulnerable to attack. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

It was discovered that dpkg 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, which may lead to leave 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 with a DoS scenario due to causing disk quota exhaustion or disk full conditions.

The advisory is shared at git.dpkg.org. This vulnerability is known as CVE-2025-6297 since 06/19/2025. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
