OpenSSL CHANGES
_______________
- Changes between 0.9.7 and 0.9.8 [xx XXX 2002]
+ Changes between 0.9.6h and 0.9.7 [XX xxx 2002]
- *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
- As these are not official, they are not included in "ALL";
- the "ECCdraft" ciphersuite group alias can be used to select them.
- [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
+ *) Change from security patch (see 0.9.6e below) that did not affect
+ the 0.9.6 release series:
- *) Add ECDH engine support.
- [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
-
- *) Add ECDH in new directory crypto/ecdh/.
-TODO: more general interface (return x coordinate, not its hash)
-TODO: bug: pad x with leading zeros if necessary
- [Douglas Stebila (Sun Microsystems Laboratories)]
-
- *) Let BN_rand_range() abort with an error after 100 iterations
- without success (which indicates a broken PRNG).
- [Bodo Moeller]
-
- *) Change BN_mod_sqrt() so that it verifies that the input value
- is really the square of the return value. (Previously,
- BN_mod_sqrt would show GIGO behaviour.)
- [Bodo Moeller]
-
- *) Add named elliptic curves over binary fields from X9.62, SECG,
- and WAP/WTLS; add OIDs that were still missing.
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) Extend the EC library for elliptic curves over binary fields
- (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
- New EC_METHOD:
-
- EC_GF2m_simple_method
-
- New API functions:
-
- EC_GROUP_new_curve_GF2m
- EC_GROUP_set_curve_GF2m
- EC_GROUP_get_curve_GF2m
- EC_POINT_set_affine_coordinates_GF2m
- EC_POINT_get_affine_coordinates_GF2m
- EC_POINT_set_compressed_coordinates_GF2m
-
- Point compression for binary fields is disabled by default for
- patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
- enable it).
-
- As binary polynomials are represented as BIGNUMs, various members
- of the EC_GROUP and EC_POINT data structures can be shared
- between the implementations for prime fields and binary fields;
- the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
- are essentially identical to their ..._GFp counterparts.
- (For simplicity, the '..._GFp' prefix has been dropped from
- various internal method names.)
-
- An internal 'field_div' method (similar to 'field_mul' and
- 'field_sqr') has been added; this is used only for binary fields.
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
- through methods ('mul', 'precompute_mult').
-
- The generic implementations (now internally called 'ec_wNAF_mul'
- and 'ec_wNAF_precomputed_mult') remain the default if these
- methods are undefined.
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) New function EC_GROUP_get_degree, which is defined through
- EC_METHOD. For curves over prime fields, this returns the bit
- length of the modulus.
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) New functions EC_GROUP_dup, EC_POINT_dup.
- (These simply call ..._new and ..._copy).
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
- Polynomials are represented as BIGNUMs (where the sign bit is not
- used) in the following functions [macros]:
-
- BN_GF2m_add
- BN_GF2m_sub [= BN_GF2m_add]
- BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
- BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
- BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
- BN_GF2m_mod_inv
- BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
- BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
- BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
- BN_GF2m_cmp [= BN_ucmp]
-
- (Note that only the 'mod' functions are actually for fields GF(2^m).
- BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
-
- For some functions, an the irreducible polynomial defining a
- field can be given as an 'unsigned int[]' with strictly
- decreasing elements giving the indices of those bits that are set;
- i.e., p[] represents the polynomial
- f(t) = t^p[0] + t^p[1] + ... + t^p[k]
- where
- p[0] > p[1] > ... > p[k] = 0.
- This applies to the following functions:
-
- BN_GF2m_mod_arr
- BN_GF2m_mod_mul_arr
- BN_GF2m_mod_sqr_arr
- BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
- BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
- BN_GF2m_mod_exp_arr
- BN_GF2m_mod_sqrt_arr
- BN_GF2m_mod_solve_quad_arr
- BN_GF2m_poly2arr
- BN_GF2m_arr2poly
-
- Conversion can be performed by the following functions:
-
- BN_GF2m_poly2arr
- BN_GF2m_arr2poly
-
- bntest.c has additional tests for binary polynomial arithmetic.
-
- Two implementations for BN_GF2m_mod_div() are available.
- The default algorithm simply uses BN_GF2m_mod_inv() and
- BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
- if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
- copyright notice in crypto/bn/bn_gf2m.c before enabling it).
-
- [Sheueling Chang Shantz and Douglas Stebila
- (Sun Microsystems Laboratories)]
-
- *) Add new error code 'ERR_R_DISABLED' that can be used when some
- functionality is disabled at compile-time.
- [Douglas Stebila <douglas.stebila@sun.com>]
-
- *) Change default behaviour of 'openssl asn1parse' so that more
- information is visible when viewing, e.g., a certificate:
-
- Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
- mode the content of non-printable OCTET STRINGs is output in a
- style similar to INTEGERs, but with '[HEX DUMP]' prepended to
- avoid the appearance of a printable string.
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
- functions
- EC_GROUP_set_asn1_flag()
- EC_GROUP_get_asn1_flag()
- EC_GROUP_set_point_conversion_form()
- EC_GROUP_get_point_conversion_form()
- These control ASN1 encoding details:
- - Curves (i.e., groups) are encoded explicitly unless asn1_flag
- has been set to OPENSSL_EC_NAMED_CURVE.
- - Points are encoded in uncompressed form by default; options for
- asn1_for are as for point2oct, namely
- POINT_CONVERSION_COMPRESSED
- POINT_CONVERSION_UNCOMPRESSED
- POINT_CONVERSION_HYBRID
-
- Also add 'seed' and 'seed_len' members to EC_GROUP with access
- functions
- EC_GROUP_set_seed()
- EC_GROUP_get0_seed()
- EC_GROUP_get_seed_len()
- This is used only for ASN1 purposes (so far).
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add 'field_type' member to EC_METHOD, which holds the NID
- of the appropriate field type OID. The new function
- EC_METHOD_get_field_type() returns this value.
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add functions
- EC_POINT_point2bn()
- EC_POINT_bn2point()
- EC_POINT_point2hex()
- EC_POINT_hex2point()
- providing useful interfaces to EC_POINT_point2oct() and
- EC_POINT_oct2point().
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Change internals of the EC library so that the functions
- EC_GROUP_set_generator()
- EC_GROUP_get_generator()
- EC_GROUP_get_order()
- EC_GROUP_get_cofactor()
- are implemented directly in crypto/ec/ec_lib.c and not dispatched
- to methods, which would lead to unnecessary code duplication when
- adding different types of curves.
- [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
-
- *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
- arithmetic, and such that modified wNAFs are generated
- (which avoid length expansion in many cases).
- [Bodo Moeller]
-
- *) Add a function EC_GROUP_check_discriminant() (defined via
- EC_METHOD) that verifies that the curve discriminant is non-zero.
-
- Add a function EC_GROUP_check() that makes some sanity tests
- on a EC_GROUP, its generator and order. This includes
- EC_GROUP_check_discriminant().
- [Nils Larsch <nla@trustcenter.de>]
-
- *) Add ECDSA in new directory crypto/ecdsa/.
-
- Add applications 'openssl ecparam' and 'openssl ecdsa'
- (these are based on 'openssl dsaparam' and 'openssl dsa').
-
- ECDSA support is also included in various other files across the
- library. Most notably,
- - 'openssl req' now has a '-newkey ecdsa:file' option;
- - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
- - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
- d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
- them suitable for ECDSA where domain parameters must be
- extracted before the specific public key;
- - ECDSA engine support has been added.
- [Nils Larsch <nla@trustcenter.de>]
+ Remote buffer overflow in SSL3 protocol - an attacker could
+ supply an oversized master key in Kerberos-enabled versions.
+ (CAN-2002-0657)
+ [Ben Laurie (CHATS)]
- *) Include some named elliptic curves, and add OIDs from X9.62,
- SECG, and WAP/WTLS. Each curve can be obtained from the new
- function
- EC_GROUP_new_by_nid(),
- and the list of available named curves can be obtained with
- EC_get_builtin_curves().
- Also add a 'curve_name' member to EC_GROUP objects, which can be
- accessed via
- EC_GROUP_set_nid()
- EC_GROUP_get_nid()
- [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
-
- Changes between 0.9.6g and 0.9.7 [XX xxx 2002]
+ *) Change the SSL kerb5 codes to match RFC 2712.
+ [Richard Levitte]
*) Make -nameopt work fully for req and add -reqopt switch.
[Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
*) The "block size" for block ciphers in CFB and OFB mode should be 1.
[Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
- *) The "block size" for block ciphers in CFB and OFB mode should be 1.
- [Steve Henson]
-
*) Make sure tests can be performed even if the corresponding algorithms
have been removed entirely. This was also the last step to make
OpenSSL compilable with DJGPP under all reasonable conditions.
# Place yourself outside of the OpenSSL source tree. In
# this example, the environment variable OPENSSL_SOURCE

Changes between 0.9.6g and 0.9.6h [xx XXX xxxx]
+ *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
+ (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
+ [Bodo Moeller]
+
+ *) Fix initialization code race conditions in
+ SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),

+ ssl2_get_cipher_by_char(),
+ ssl3_get_cipher_by_char().
+ [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
+
*) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
the cached sessions are flushed, as the remove_cb() might use ex_data
contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
overflow checks added in 0.9.6e. This prevents DoS (the
assertions could call abort()).
[Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]

Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
*) Add various sanity checks to asn1_get_length() to reject
too small for 64 bit platforms. (CAN-2002-0655)
[Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
