Multiple directory traversal vulnerabilities in dpkg-source in dpkg-dev 1.3.0 allow remote attackers to modify files outside of the intended directories via a source package with a crafted Index: pseudo-header in conjunction with (1) missing --- and +++ header lines or (2) a +++ header line with a blank pathname.
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.
