Ubuntu Security Notice USN-1366-1

devscripts vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

debdiff, a part of devscripts, could be made to run programs as your login if
it opened a specially crafted file.

Software Description:
- devscripts: scripts to make the life of a Debian Package maintainer easier

Details:

Paul Wise discovered that debdiff did not properly sanitize its input when
processing .dsc and .changes files. If debdiff processed a crafted file, an
attacker could execute arbitrary code with the privileges of the user invoking
the program. (CVE-2012-0210)

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 input
when processing filename parameters. If debdiff processed a crafted filename
parameter, an attacker could execute arbitrary code with the privileges of the
user invoking the program. (CVE-2012-0212)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
  devscripts                      2.11.1ubuntu3.1

Ubuntu 11.04:
  devscripts                      2.10.69ubuntu2.1

Ubuntu 10.10:
  devscripts                      2.10.67ubuntu1.1

Ubuntu 10.04 LTS:
  devscripts                      2.10.61ubuntu5.1

Ubuntu 8.04 LTS:
  devscripts                      2.10.11ubuntu5.8.04.5

In general, a standard system update will make all the necessary changes.
