    devscripts vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in devscripts.
    
    Software Description:
    - devscripts: scripts to make the life of a Debian Package maintainer easier
    
    Details:
    
    Raphael Geissert discovered that the debdiff.pl tool incorrectly handled
    shell metacharacters. If a user or automated system were tricked into
    processing a specially crafted filename, a remote attacher could possibly
    execute arbitrary code. (CVE-2012-0212)
    
    Raphael Geissert discovered that the dscverify tool incorrectly escaped
    arguments to external commands. If a user or automated system were tricked
    into processing specially crafted files, a remote attacher could possibly
    execute arbitrary code. (CVE-2012-2240)
    
    Raphael Geissert discovered that the dget tool incorrectly performed input
    validation. If a user or automated system were tricked into processing
    specially crafted files, a remote attacher could delete arbitrary files.
    (CVE-2012-2241)
    
    Raphael Geissert discovered that the dget tool incorrectly escaped
    arguments to external commands. If a user or automated system were tricked
    into processing specially crafted files, a remote attacher could possibly
    execute arbitrary code. This issue only affected Ubuntu 10.04 LTS and
    Ubuntu 11.04. (CVE-2012-2242)
    
    Jim Meyering discovered that the annotate-output tool incorrectly handled
    temporary files. A local attacker could use this flaw to alter files being
    processed by the annotate-output tool. On Ubuntu 11.04 and later, this
    issue was mitigated by the Yama kernel symlink restrictions.
    (CVE-2012-3500)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      devscripts                      2.11.6ubuntu1.4
    
    Ubuntu 11.10:
      devscripts                      2.11.1ubuntu3.2
    
    Ubuntu 11.04:
      devscripts                      2.10.69ubuntu2.2
    
    Ubuntu 10.04 LTS:
      devscripts                      2.10.61ubuntu5.3
    
    In general, a standard system update will make all the necessary changes.
