Debian Security Advisory DSA-1726-1 security@debian.org

- ------------------------------------------------------------------------

Package : python-crypto
Vulnerability : buffer overflow
Problem type : local(remote)
Debian-specific: no
CVE Id(s) : CVE-2009-0544

Mike Wiacek discovered that a buffer overflow in the ARC2 implementation
of Python Crypto, a collection of cryptographic algorithms and protocols
for Python allows denial of service and potentially the execution of
arbitrary code.

For the stable distribution (lenny), this problem has been fixed in
version 2.0.1+dfsg1-2.3+lenny0.

Due to a technical limitation in the Debian archive management scripts
the update for the old stable distribution (etch) cannot be released
synchronously. It will be fixed in version 2.0.1+dfsg1-1.2+etch0 soon.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your python-crypto 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 GNU/Linux 5.0 alias lenny
- --------------------------------

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