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.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
