Package        : jazip
Vulnerability  : local root exploit and buffer overflow
Debian-specific: no

With older versions of jazip a user could gain root access for members
of the floppy group to the local machine.  The interface doesn't run
as root anymore and this very exploit was prevented.  The program now
also truncates DISPLAY to 256 characters if it is bigger, which closes
the buffer overflow (within xforms).

We recommend you upgrade your jazip package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.
