Dotmesh is a git-like command-line interface for capturing, organizing and sharing application states. In versions 0.8.1 and prior, the unsafe handling of symbolic links in an unpacking routine may
enable attackers to read and/or write to arbitrary locations outside the
designated target folder.Β The routine untarFile
attempts to guard against creating symbolic links that point outside the directory a tar archive is extracted to. However, a malicious tarball first linking subdir/parent
to ..
(allowed, because subdir/..
falls within the archive root) and then linking subdir/parent/escapes
to ..
results in a symbolic link pointing to the tarballβs parent directory, contrary to the routineβs goals. This issue may lead to arbitrary file write (with same permissions as the program running the unpack operation) if the attacker can control the archive file. Additionally, if the attacker has read access to the unpacked files, they may be able to read arbitrary system files the parent process has permissions to read. As of time of publication, no patch for this issue is available.
