"Several vulnerabilities have been discovered in debdiff, a script used
to compare two Debian packages, which is part of the devscripts
package. The following Common Vulnerabilities and Exposures project
ids have been assigned to identify them :

  - CVE-2012-0210 :
    Paul Wise discovered that due to insufficient input
    sanitising when processing .dsc and .changes files, it
    is possible to execute arbitrary code and disclose
    system information.

  - CVE-2012-0211 :
    Raphael Geissert discovered that it is possible to
    inject or modify arguments of external commands when
    processing source packages with specially-named tarballs
    in the top-level directory of the .orig tarball,
    allowing arbitrary code execution.

  - CVE-2012-0212 :
    Raphael Geissert discovered that it is possible to
    inject or modify arguments of external commands when
    passing as argument to debdiff a specially-named file,
    allowing arbitrary code execution."
