Package        : openssl
Vulnerability  : buffer overflow
Problem type   : remote
Debian-specific: no
Debian Bug     : 603709
CVE Id(s)      : CVE-2010-3864

A flaw has been found in the OpenSSL TLS server extension code parsing
which on affected servers can be exploited in a buffer overrun attack.
This allows an attacker to cause an appliation crash or potentially to
execute arbitrary code.

However, not all OpenSSL based SSL/TLS servers are vulnerable: A server
is vulnerable if it is multi-threaded and uses OpenSSL's internal caching
mechanism.  In particular the Apache HTTP server (which never uses OpenSSL
internal caching) and Stunnel (which includes its own workaround) are NOT
affected.

This upgrade fixes this issue. After the upgrade, any services using the
openssl libraries need to be restarted. The checkrestart script from the
debian-goodies package or lsof can help to find out which services need
to be restarted.

A note to users of the tor packages from the Debian backports or Debian
volatile: This openssl update causes problems with some versions of tor.
You need to update to tor 0.2.1.26-4~bpo50+1 or 0.2.1.26-1~lennyvolatile2,
respectively. The tor package version 0.2.0.35-1~lenny2 from Debian stable
is not affected by these problems.

For the stable distribution (lenny), the problem has been fixed in
openssl version 0.9.8g-15+lenny9.

For the testing distribution (squeeze) and the unstable distribution
(sid), this problem has been fixed in version 0.9.8o-3.

We recommend that you upgrade your openssl packages.

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)
- -----------------------------------------

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