Description

autoar-extractor.c in GNOME gnome-autoar through 0.2.4, as used by GNOME Shell, Nautilus, and other software, allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink to a directory outside of the intended extraction location.

Techniques & Countermeasures

  • CWE-22•Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

    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.

  • CWE-59•Improper Link Resolution Before File Access ('Link Following')

    The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
