Debian: DSA-3562-1 Critical Tardiff Shell Injection and File Overwrite

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.
