A path traversal vulnerability affects jefferson's JFFS2 filesystem extractor. By crafting malicious JFFS2 files, attackers could force jefferson to write outside of the extraction directory.This issue affects jefferson: before 0.4.1.
Solution:
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.
