devscripts - several

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.

For the stable distribution (squeeze), these problems have been fixed in
version 2.10.69+squeeze2.

For the testing distribution (wheezy), these problems will be fixed soon.

For the unstable distribution (sid), these problems will be fixed in
version 2.11.4.

We recommend that you upgrade your devscripts packages.
