* [CVE-2012-2417] Fix LP#985164: insecure ElGamal key generation.
(thanks: Legrandin)
In the ElGamal schemes (for both encryption and signatures), g is
supposed to be the generator of the entire Z^*_p group. However, in
PyCrypto 2.5 and earlier, g is more simply the generator of a random
sub-group of Z^*_p.
The result is that the signature space (when the key is used for
signing) or the public key space (when the key is used for encryption)
may be greatly reduced from its expected size of log(p) bits, possibly
down to 1 bit (the worst case if the order of g is 2).
While it has not been confirmed, it has also been suggested that an
attacker might be able to use this fact to determine the private key.
Anyone using ElGamal keys should generate new keys as soon as practical.
Any additional information about this bug will be tracked at
https://bugs.launchpad.net/pycrypto/+bug/985164
* Huge documentation cleanup (thanks: Legrandin).
* Added more tests, including test vectors from NIST 800-38A
(thanks: Legrandin)
* Remove broken MODE_PGP, which never actually worked properly.
A new mode, MODE_OPENPGP, has been added for people wishing to write
OpenPGP implementations. Note that this does not implement the full
OpenPGP specification, only the "OpenPGP CFB mode" part of that
specification.

even if zonelist has not changed.

AuthCAS aims at providing a Perl API to Yale's Central Authentication System

Fix seuciry problem of CVE-2012-2337.
What's new in Sudo 1.7.9p1?
* Fixed a bug when matching against an IP address with an associated
netmask in the sudoers file. In certain circumstances, this
could allow users to run commands on hosts they are not authorized
for.
What's new in Sudo 1.7.9?
* Fixed a false positive in visudo strict mode when aliases are
in use.
* The line on which a syntax error is reported in the sudoers file
is now more accurate. Previously it was often off by a line.
* The #include and #includedir directives in sudoers now support
relative paths. If the path is not fully qualified it is expected
to be located in the same directory of the sudoers file that is
including it.
* visudo will now fix the mode on the sudoers file even if no changes
are made unless the -f option is specified.
* The "use_loginclass" sudoers option works properly again.
* For LDAP-based sudoers, values in the search expression are now
escaped as per RFC 4515.
* Fixed a race condition when I/O logging is not enabled that could
result in tty-generated signals (e.g. control-C) being received
by the command twice.
* If none of the standard input, output or error are connected to
a tty device, sudo will now check its parent's standard input,
output or error for the tty name on systems with /proc and BSD
systems that support the KERN_PROC_PID sysctl. This allows
tty-based tickets to work properly even when, e.g. standard
input, output and error are redirected to /dev/null.
* Fixed a bug where a pattern like "/usr/*" included /usr/bin/ in
the results, which would be incorrectly be interpreted as if the
sudoers file had specified a directory.
* "visudo -c" will now list any include files that were checked
in addition to the main sudoers file when everything parses OK.
* Users that only have read-only access to the sudoers file may
now run "visudo -c". Previously, write permissions were required
even though no writing is down in check-only mode.
What's new in Sudo 1.7.8p2?
* Fixed a crash in the monitor process on Solaris when NOPASSWD
was specified or when authentication was disabled.
The Cryptokit library for Objective Caml provides a variety of
cryptographic primitives that can be used to implement cryptographic
protocols in security-sensitive applications. The primitives provided
include:
Symmetric-key cryptography: AES, DES, Triple-DES, ARCfour, in ECB,
CBC, CFB and OFB modes. Public-key cryptography: RSA encryption and
signature; Diffie-Hellman key agreement. Hash functions and MACs:
SHA-1, MD5, and MACs based on AES and DES. Random number generation.
Encodings and compression: base 64, hexadecimal, Zlib compression.
Additional ciphers and hashes can easily be used in conjunction
with the library. In particular, basic mechanisms such as chaining
modes, output buffering, and padding are provided by generic classes
that can easily be composed with user-provided ciphers. More
generally, the library promotes a "Lego"-like style of constructing
and composing transformations over character streams.

The Google Authenticator includes implementations of one-time passcode
generators for several mobile platforms as well as a pluggable
authentication module (PAM). One-time passcodes are generated using
open standards developed by the Initiative for Open Authentication
(OATH) (which is unrelated to OAuth).
These implementations support the HMAC-Based One-time Password (HOTP)
algorithm specified in RFC 4226 and the Time-based One-time Password
(TOTP) algorithm specified in RFC 6238.
Because upstream does not provide a distribution file (yet), I have
pre-packaged the sources myself as of today and uploaded them to
ftp.n.o under my own directory. This explains the 0.0 prefix in the
version number, because if upstream starts providing distfiles with
proper versioning, we don't want our date stamp to be "above" all
official versions.
tool that, in addition to basic syntactic and semantic zone checks,
includes DNSSEC signature verification and NSEC/NSEC3 chain validation,
as well a number of optional policy checks on the zone.
Security fix for CVS-2012-2131.
Changes between 0.9.8v and 0.9.8w [23 Apr 2012]
*) The fix for CVE-2012-2110 did not take into account that the
'len' argument to BUF_MEM_grow and BUF_MEM_grow_clean is an
int in OpenSSL 0.9.8, making it still vulnerable. Fix by
rejecting negative len parameter. (CVE-2012-2131)

Upstream changes:
## ssh 1.7.13 (2012-02-13)
* #5: Moved a `fcntl` import closer to where it's used to help avoid
`ImportError` problems on Windows platforms. Thanks to Jason Coombs for the
catch + suggested fix.
* #4: Updated implementation of WinPageant integration to work on 64-bit
Windows. Thanks again to Jason Coombs for the patch.
