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

    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.
