Directory traversal vulnerability in the unpacking functionality in dpkg before 1.15.9, 1.16.x before 1.16.13, and 1.17.x before 1.17.8 allows remote attackers to write arbitrary files via a crafted source package, related to "C-style filename quoting."
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.
