when processing .dsc and .changes files. If debdiff processed a
crafted file, an attacker could execute arbitrary code with the

Raphael Geissert discovered that debdiff did not properly sanitize its
input when processing source packages. If debdiff processed an
original source tarball, with crafted filenames in the top-level
directory, an attacker could execute arbitrary code with the
privileges of the user invoking the program. (CVE-2012-0211)

Raphael Geissert discovered that debdiff did not properly sanitize its

crafted filename parameter, an attacker could execute arbitrary code
with the privileges of the user invoking the program. (CVE-2012-0212).
