    CVE-2025-6297 (GCVE-0-2025-6297)

    Vulnerability from cvelistv5 – Published: 2025-07-01 16:16 – Updated: 2026-07-08 07:48
    VLAI
    Title
    dpkg-deb: Fix cleanup for control member with restricted directories
    Summary
    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.

    CVE-2022-1664 (GCVE-0-2022-1664)

    Vulnerability from cvelistv5 – Published: 2022-05-26 08:20 – Updated: 2024-09-17 02:16
    VLAI
    Title
    directory traversal for in-place extracts with untrusted v2 and v3 source packages with debian.tar
    Summary
    Dpkg::Source::Archive in dpkg, the Debian package management system, before version 1.21.8, 1.20.10, 1.19.8, 1.18.26 is prone to a directory traversal vulnerability. When extracting untrusted source packages in v2 and v3 source package formats that include a debian.tar, the in-place extraction can lead to directory traversal situations on specially crafted orig.tar and debian.tar tarballs.
    Severity
    No CVSS data available.
