Debian Security Advisory                             security@debian.org

Package        : xpdf
Problem type   : local exploit
Debian-specific: no

xpdf as distributed in Debian GNU/Linux 2.2 suffered from two problems:
1. creation of temporary files was not done safely which made xpdf
vulnerable to a symlink attack.
2. when handling URLs in documents no checking was done for shell
metacharacters before starting the browser. This makes it possible
to construct a document which cause xpdf to run arbitrary commands
when the user views an URL.

Both problems have been fixed in version 0.90-7, and we recommend you
upgrade your xpdf 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 the alpha, arm, i386, m68k, powerpc and sparc
  architectures. At this moment no fixed package is available for arm
  machines.
