Package        : glibc
Problem type   : buffer overflow
Debian-specific: no

A buffer overflow has been found in the globbing code for glibc.
This code which is used to glob patterns for filenames and is
commonly used in applications like shells and FTP servers.

This has been fixed in versino 2.1.3-20 and we recommend that
you upgrade your libc package immediately.

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


Debian GNU/Linux 2.2 alias potato

  Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
