Debian: New file packages fix arbitrary code execution

An integer underflow bug has been found in the file_printf function in file, a tool to determine file types based analysis of file content. The bug could allow an attacker to execute arbitrary code by inducing a local user to examine a specially crafted file that triggers a buffer overflow. Fixed packages are available from security.debian.org.

An integer underflow bug has been found in the file_printf function in
file, a tool to determine file types based analysis of file content.
The bug could allow an attacker to execute arbitrary code by inducing a
local user to examine a specially crafted file that triggers a buffer
overflow.

For the stable distribution (sarge), this problem has been fixed in
version 4.12-1sarge1.

For the upcoming stable distribution (etch), this problem has been fixed in
version 4.17-5etch1.

For the unstable distribution (sid), this problem has been fixed in
4.20-1.

We recommend that you upgrade your file package.

Upgrade instructions
- --------------------

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

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

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

Debian (testing)
- ----------------

Testing updates are available for alpha, amd64, arm, hppa, i386, ia64, m68k, mips, mipsel, powerpc, s390 and sparc.
