CVE-2023-7207

Estado: AnalizadaMedia (4.9)—

Debian's cpio contains a path traversal vulnerability. This issue was introduced by reverting CVE-2015-1197 patches which had caused a regression in --no-absolute-filenames. Upstream has since provided a proper fix to --no-absolute-filenames.

CVSS

Probabilidad de explotación (EPSS)
