    Jonathan Dolle reported a design error in HTTP::Body, a Perl module for
    processing data from HTTP POST requests. The HTTP body multipart parser
    creates temporary files which preserve the suffix of the uploaded file.
    An attacker able to upload files to a service that uses
    HTTP::Body::Multipart could potentially execute commands on the server
    if these temporary filenames are used in subsequent commands without
    further checks.
    
    This update restricts the possible suffixes used for the created
    temporary files.
    
    The oldstable distribution (squeeze) is not affected by this problem.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.11-1+deb7u1.
    
    For the testing distribution (jessie), this problem has been fixed in
    version 1.17-2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.17-2.
    
    We recommend that you upgrade your libhttp-body-perl packages.
