Package        : tardiff
CVE ID         : CVE-2015-0857 CVE-2015-0858

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.

For the stable distribution (jessie), these problems have been fixed in
version 0.1-2+deb8u2.

For the unstable distribution (sid), these problems have been fixed in
version 0.1-5 and partially in earlier versions.

We recommend that you upgrade your tardiff packages.
