    Multiple vulnerabilities have been discovered in devscripts, a set of
    scripts to make the life of a Debian Package maintainer easier.
    The following Common Vulnerabilities and Exposures project ids have
    been assigned to identify them:
    
    CVE-2012-2240:
    
        Raphael Geissert discovered that dscverify does not perform
        sufficient validation and does not properly escape arguments to
        external commands, allowing a remote attacker (as when dscverify is
        used by dget) to execute arbitrary code.
    
    CVE-2012-2241:
    
        Raphael Geissert discovered that dget allows an attacker to delete
        arbitrary files when processing a specially-crafted .dsc or
        .changes file, due to insuficient input validation.
    
    CVE-2012-2242:
    
        Raphael Geissert discovered that dget does not properly escape
        arguments to external commands when processing .dsc and .changes
        files, allowing an attacker to execute arbitrary code.
        This issue is limited with the fix for CVE-2012-2241, and had
        already been fixed in version 2.10.73 due to changes to the code,
        without considering its security implications.
    
    CVE-2012-3500:
    
        Jim Meyering, Red Hat, discovered that annotate-output determines
        the name of temporary named pipes in a way that allows a local
        attacker to make it abort, leading to denial of service.
    
    
    Additionally, a regression in the exit code of debdiff introduced in
    DSA-2409-1 has been fixed.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 2.10.69+squeeze4.
    
    For the testing distribution (wheezy), these problems will be fixed
    soon.
    
    For the unstable distribution (sid), these problems will be fixed in
    version 2.12.3.
    
    We recommend that you upgrade your devscripts packages.
