Package        : squid
Vulnerability  : insecure tempfile hole
Debian-specific: no

WireX discovered a potential temporary file race condition in the way
that squid sends out email messages notifying the administrator about
updating the program.  This could lead to arbitrary files to get
overwritten.  However the code would only be executed if running a
very bleeding edge release of squid, running a server whose time is
set some number of months in the past and squid is crashing.  Read it
as hardly to exploit.  This version also containes more upstream
bugfixes wrt. dots in hostnames and unproper HTML quoting.

We recommend you upgrade your squid package..

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.


Debian GNU/Linux 2.2 alias potato
- ------------------------------------

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