Several vulnerabilities were discovered in tardiff, a tarball comparison tool. The Common Vulnerabilities and Exposures project identifies the following problems :
CVE-2015-0857 Rainer Mueller and Florian Weimer discovered that tardiff is prone to shell command injections via shell meta-characters in filenames in tar files or via shell meta-characters in the tar filename itself.
CVE-2015-0858 Florian Weimer discovered that tardiff uses predictable temporary directories for unpacking tarballs. A malicious user can use this flaw to overwrite files with permissions of the user running the tardiff command line tool.
