FEDORA-2008-10540
None
--------------------------------------------------------------------------------

Name        : openvpn
Product     : Fedora 10
Version     : 2.1
Release     : 0.29.rc15.fc10
URL         : http://openvpn.net/
Summary     : A full-featured SSL VPN solution
Description :
OpenVPN is a robust and highly flexible tunneling application that uses all
of the encryption, authentication, and certification features of the
OpenSSL library to securely tunnel IP networks over a single UDP or TCP
port.  It can use the Marcus Franz Xaver Johannes Oberhumer's LZO library
for compression.

--------------------------------------------------------------------------------
Update Information:

2008.11.19 -- Version 2.1_rc15    * Fixed issue introduced in 2.1_rc14 that may
cause a    segfault when a --plugin module is used.    * Added server-side
--opt-verify option: clients that connect    with options that are incompatible
with those of the server    will be disconnected (without this option,
incompatible    clients would trigger a warning message in the server log    but
would not be disconnected).    * Added --tcp-nodelay option: Macro that sets
TCP_NODELAY socket    flag on the server as well as pushes it to connecting
clients.    * Minor options check fix: --no-name-remapping is a    server-only
option and should therefore generate an    error when used on the client.    *
Added --prng option to control PRNG (pseudo-random    number generator)
parameters.  In previous OpenVPN    versions, the PRNG was hardcoded to use the
SHA1    hash.  Now any OpenSSL hash may be used.  This is    part of an effort
to remove hardcoded references to    a specific cipher or cryptographic hash
algorithm.    * Cleaned up man page synopsis.    2008.11.16 -- Version 2.1_rc14
* Added AC_GNU_SOURCE to configure.ac to enable struct ucred,    with the goal
of fixing a build issue on Fedora 9 that was    introduced in 2.1_rc13.    *
Added additional method parameter to --script-security to preserve    backward
compatibility with system() call semantics used in OpenVPN    2.1_rc8 and
earlier.  To preserve backward compatibility use:        script-security 3
system    * Added additional warning messages about --script-security 2    or
higher being required to execute user-defined scripts or    executables.    *
Windows build system changes:      Modified Windows domake-win build system to
write all openvpn.nsi    input files to gen, so that gen can be disconnected
from    the rest of the source tree and makensis openvpn.nsi will    still
function correctly.      Added additional SAMPCONF_(CA|CRT|KEY) macros to
settings.in    (commented out by default).      Added optional files
SAMPCONF_CONF2 (second sample configuration    file) and SAMPCONF_DH (Diffie-
Helman parameters) to Windows    build system, and may be defined in
settings.in.    * Extended Management Interface "bytecount" command    to work
when OpenVPN is running as a server.    Documented Management Interface
"bytecount" command in    management/management-notes.txt.    * Fixed
informational message in ssl.c to properly indicate    deferred authentication.
* Added server-side --auth-user-pass-optional directive, to allow    connections
by clients that do not specify a username/password, when a    user-defined
authentication script/module is in place (via    --auth-user-pass-verify,
--management-client-auth, or a plugin module).    * Changes to easy-
rsa/2.0/pkitool and related openssl.cnf:      Calling scripts can set the
KEY_NAME environmental variable to set    the "name" X509 subject field in
generated certificates.      Modified pkitool to allow flexibility in separating
the Common Name    convention from the cert/key filename convention.      For
example:      KEY_CN="James's Laptop" KEY_NAME="james" ./pkitool james      will
create a client certificate/key pair of james.crt/james.key    having a Common
Name of "James's Laptop" and a Name of "james".    * Added --no-name-remapping
option to allow Common Name, X509 Subject,    and username strings to include
any printable character including    space, but excluding control characters
such as tab, newline, and    carriage-return (this is important for
compatibility with external    authentication systems).      As a related
change, added --status-version 3 format (and "status 3"    in the management
interface) which uses the version 2 format except    that tabs are used as
delimiters instead of commas so that there    is no ambiguity when parsing a
Common Name that contains a comma.      Also, save X509 Subject fields to
environment, using the naming    convention:
X509_{cert_depth}_{name}={value}      This is to avoid ambiguities when parsing
out the X509 subject string    since "/" characters could potentially be used in
the common name.    * Fixed some ifconfig-pool issues that precluded it from
being combined    with --server directive.      Now, for example, we can
configure thusly:        server 10.8.0.0 255.255.255.0 nopool      ifconfig-pool
10.8.0.2 10.8.0.99 255.255.255.0      to have ifconfig-pool manage only a subset
of the VPN subnet.    * Added config file option "setenv FORWARD_COMPATIBLE 1"
to relax    config file syntax checking to allow directives for future OpenVPN
versions to be ignored.    2008.10.07 -- Version 2.1_rc13    * Bundled OpenSSL
0.9.8i with Windows installer.    * Management interface can now listen on a
unix    domain socket, for example:        management /tmp/openvpn unix
Also added management-client-user and management-client-group    directives to
control which processes are allowed to connect    to the socket.    * Copyright
change to OpenVPN Technologies, Inc.    2008.09.23 -- Version 2.1_rc12    *
Patched Makefile.am so that the new t_cltsrv-down.sh script becomes    part of
the tarball (Matthias Andree).    * Fixed --lladdr bug introduced in 2.1-rc9
where input validation code    was incorrectly expecting the lladdr parameter to
be an IP address    when it is actually a MAC address (HoverHell).    2008.09.14
-- Version 2.1_rc11    * Fixed a bug that can cause SSL/TLS negotiations in UDP
mode    to fail if UDP packets are dropped.    2008.09.10 -- Version 2.1_rc10
* Added "--server-bridge" (without parameters) to enable    DHCP proxy mode:
Configure server mode for ethernet    bridging using a DHCP-proxy, where clients
talk to the    OpenVPN server-side DHCP server to receive their IP address
allocation and DNS server addresses.    * Added "--route-gateway dhcp", to
enable the extraction    of the gateway address from a DHCP negotiation with the
OpenVPN server-side LAN.    * Fixed minor issue with --redirect-gateway bypass-
dhcp or bypass-dns    on Windows.  If the bypass IP address is 0.0.0.0 or
255.255.255.255,    ignore it.    * Warn when ethernet bridging that the IP
address of the bridge adapter    is probably not the same address that the LAN
adapter was set to    previously.    * When running as a server, warn if the LAN
network address is    the all-popular 192.168.[0|1].x, since this condition
commonly    leads to subnet conflicts down the road.    * Primarily on the
client, check for subnet conflicts between    the local LAN and the VPN subnet.
* Added a 'netmask' parameter to get_default_gateway, to return    the netmask
of the adapter containing the default gateway.    Only implemented on Windows so
far.  Other platforms will    return 255.255.255.0.  Currently the netmask
information is    only used to warn about subnet conflicts.    * Minor fix to
cryptoapi.c to not compile itself unless USE_CRYPTO    and USE_SSL flags are
enabled (Alon Bar-Lev).    * Updated openvpn/t_cltsrv.sh (used by "make check")
to conform to new    --script-security rules.  Also adds retrying if the
addresses are in    use (Matthias Andree).    * Fixed build issue with
./configure --disable-socks --disable-http.    * Fixed separate compile errors
in options.c and ntlm.c that occur    on strict C compilers (such as old
versions of gcc) that require    that C variable declarations occur at the start
of a {} block,    not in the middle.    * Workaround bug in OpenSSL 0.9.6b
ASN1_STRING_to_UTF8, which    the new implementation of extract_x509_field_ssl
depends on.    * LZO compression buffer overflow errors will now invalidate
the packet rather than trigger a fatal assertion.    * Fixed minor compile issue
in ntlm.c (mid-block declaration).    * Added --allow-pull-fqdn option which
allows client to pull DNS names    from server (rather than only IP address) for
--ifconfig, --route, and    --route-gateway.  OpenVPN versions 2.1_rc7 and
earlier allowed DNS names    for these options to be pulled and translated to IP
addresses by default.    Now --allow-pull-fqdn will be explicitly required on
the client to enable    DNS-name-to-IP-address translation of pulled options.
* 2.1_rc8 and earlier did implicit shell expansion on script    arguments since
all scripts were called by system().    The security hardening changes made to
2.1_rc9 no longer    use system(), but rather use the safer execve or
CreateProcess    system calls.  The security hardening also introduced a
backward incompatibility with 2.1_rc8 and earlier in that    script parameters
were no longer shell-expanded, so    for example:        client-connect "docc
CLIENT-CONNECT"      would fail to work because execve would try to execute    a
script called "docc CLIENT-CONNECT" instead of "docc"    with "CLIENT-CONNECT"
as the first argument.      This patch fixes the issue, bringing the script
argument    semantics back to pre 2.1_rc9 behavior in order to preserve
backward compatibility while still using execve or CreateProcess    to execute
the script/executable.    * Modified ip_or_dns_addr_safe, which validates pulled
DNS names,    to more closely conform to RFC 3696:      (1) DNS name length must
not exceed 255 characters      (2) DNS name characters must be limited to
alphanumeric,        dash ('-'), and dot ('.')    * Fixed bug in intra-session
TLS key rollover that was introduced with    deferred authentication features in
2.1_rc8.
