Fix symlink path traversal in rdsqaushfs

2021-08-12T16:24:38+00:00

If rdsquashfs unpacks a directory tree that contains a symlink, followed by something else with the exact same name, it will follow the symlink and can be tricked into writing to an arbitrary filesystem location controlled by the SquashFS image. Because there might actually be a reasonable use case, where an image is unpacked into an directory existing directory tree, with symlinks that should be followed, this is solved as follows: - Before unpacking, recursively sort the directory by filename. - FAIL if (after sorting) two consequtive entries at the same hierarchy level have the same name. This solution is more generic and prevents the unpacker from accessing the same thing twice in generall, thus also excluding the symlink issue. Hardlinks are already unfolded into duplicate tree nodes by the tree reader (with loop detection) so that should not prompt further issues. Signed-off-by: David Oberhollenzer

tar2sqfs: Fix integer truncation issue when appending data to a tarball

2021-07-09T17:51:43+00:00

The data is processed 2G at a time to avoid this exact issue, but the check was skipped on 64 bit systems, since the function *used to* use size_t instead of sqfs_u32. This commit removes the second check. Signed-off-by: David Oberhollenzer

Fix: libsquashfs: add sqfs_free() function

2021-04-08T10:04:33+00:00

On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation. Signed-off-by: David Oberhollenzer

fstree_from_file: Implement basic file globbing

2021-02-19T16:35:07+00:00

The base path is passed to the fstree_from_file function and in turn to the individual callbacks. The line parsing function is modified to allow '*' as mode, uid and gid for specifically marked callbacks. A glob callback is added that internally uses the fstree_from_dir scanning functions in combination with a filter callback. Directory scanning flags are parsed from the extra arguments before interpreting it as a path fragment. Signed-off-by: David Oberhollenzer
