NONE Summary
OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL 1.0.2n. OpenSSL 1.1.0 is not affected.

No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen.

[CVE-2017-3737] There is an overflow bug in the x86_64 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). [CVE-2017-3738] This bug only affects FreeBSD 11.x. Impact : Applications with incorrect error handling may inappropriately pass unencrypted data. [CVE-2017-3737] Mishandling of carry propagation will produce incorrect output, and make it easier for a remote attacker to obtain sensitive private-key information. No EC algorithms are affected and analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.

The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. OpenSSL version 1.0.2b-1.0.2m are affected. Fixed in OpenSSL 1.0.2n. OpenSSL 1.1.0 is not affected. (CVE-2017-3737) - There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). Note: The impact from this issue is similar to CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL version 1.0.2-1.0.2m and 1.1.0-1.1.0g are affected. Fixed in OpenSSL 1.0.2n. Due to the low severity of this issue we are not issuing a new release of OpenSSL 1.1.0 at this time. The fix will be included in OpenSSL 1.1.0h when it becomes available. The fix is also available in commit e502cc86d in the OpenSSL git repository. (CVE-2017-3738) - There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. No EC algorithms are affected.

This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. (CVE-2017-3736) - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled error condition. (CVE-2006-2937) - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) public exponent or (2) public modulus values in X.509 certificates that require extra time to process when using RSA signature verification. (CVE-2006-2940) - Buffer overflow in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions has unspecified impact and remote attack vectors involving a long list of ciphers. (CVE-2006-3738) - OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8 before 0.9.8c, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents OpenSSL from correctly verifying X.509 and other certificates that use PKCS #1. (CVE-2006-4339) - The get_server_hello function in the SSLv2 client code in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows remote servers to cause a denial of service (client crash) via unknown vectors that trigger a null pointer dereference. (CVE-2006-4343) - The BN_from_montgomery function in crypto/bn/bn_mont.c in OpenSSL 0.9.8e and earlier does not properly perform Montgomery multiplication, which might allow local users to conduct a side-channel attack and retrieve RSA private keys. (CVE-2007-3108) - Off-by-one error in the DTLS implementation in OpenSSL 0.9.8 before 0.9.8f allows remote attackers to execute arbitrary code via unspecified vectors. (CVE-2007-4995) - Off-by-one error in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f, might allow remote attackers to execute arbitrary code via a crafted packet that triggers a one-byte buffer underflow. NOTE: this issue was introduced as a result of a fix for CVE-2006-3738. As of 20071012, it is unknown whether code execution is possible. (CVE-2007-5135) - Double free vulnerability in OpenSSL 0.9.8f and 0.9.8g, when the TLS server name extensions are enabled, allows remote attackers to cause a denial of service (crash) via a malformed Client Hello packet. NOTE: some of these details are obtained from third party information. (CVE-2008-0891) - OpenSSL 0.9.8f and 0.9.8g allows remote attackers to cause a denial of service (crash) via a TLS handshake that omits the Server Key Exchange message and uses particular cipher suites, which triggers a NULL pointer dereference. (CVE-2008-1672) - The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote attackers to cause a denial of service (memory consumption) via a large series of future epoch DTLS records that are buffered in a queue, aka DTLS record buffer limitation bug. (CVE-2009-1377) - Multiple memory leaks in the dtls1_process_out_of_seq_message function in ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote attackers to cause a denial of service (memory consumption) via DTLS records that (1) are duplicates or (2) have sequence numbers much greater than current sequence numbers, aka DTLS fragment handling memory leak. (CVE-2009-1378) - Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote attackers to cause a denial of service (openssl s_client crash) and possibly have unspecified other impact via a DTLS packet, as demonstrated by a packet from a server that uses a crafted server certificate. (CVE-2009-1379) - The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post- renegotiation context, related to a plaintext injection attack, aka the Project Mogul issue. (CVE-2009-3555) - Memory leak in the zlib_stateful_finish function in crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and 1.0.0 Beta through Beta 4 allows remote attackers to cause a denial of service (memory consumption) via vectors that trigger incorrect calls to the CRYPTO_cleanup_all_ex_data function, as demonstrated by use of SSLv3 and PHP with the Apache HTTP Server, a related issue to CVE-2008-1678. (CVE-2009-4355) - The Cryptographic Message Syntax (CMS) implementation in crypto/cms/cms_asn1.c in OpenSSL before 0.9.8o and 1.x before 1.0.0a does not properly handle structures that contain OriginatorInfo, which allows context-dependent attackers to modify invalid memory locations or conduct double-free attacks, and possibly execute arbitrary code, via unspecified vectors. (CVE-2010-0742) - RSA verification recovery in the EVP_PKEY_verify_recover function in OpenSSL 1.x before 1.0.0a, as used by pkeyutl and possibly other applications, returns uninitialized memory upon failure, which might allow context-dependent attackers to bypass intended key requirements or obtain sensitive information via unspecified vectors. NOTE: some of these details are obtained from third party information. (CVE-2010-1633) - Multiple race conditions in ssl/t1_lib.c in OpenSSL 0.9.8f through 0.9.8o, 1.0.0, and 1.0.0a, when multi- threading and internal caching are enabled on a TLS server, might allow remote attackers to execute arbitrary code via client data that triggers a heap- based buffer overflow, related to (1) the TLS server name extension and (2) elliptic curve cryptography. (CVE-2010-3864) - OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not properly prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the downgrade to an unintended cipher via vectors involving sniffing network traffic to discover a session identifier. (CVE-2010-4180) - ssl/t1_lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0 through 1.0.0c allows remote attackers to cause a denial of service (crash), and possibly obtain sensitive information in applications that use OpenSSL, via a malformed ClientHello handshake message that triggers an out-of-bounds memory access, aka OCSP stapling vulnerability. (CVE-2011-0014) - crypto/x509/x509_vfy.c in OpenSSL 1.0.x before 1.0.0e does not initialize certain structure members, which makes it easier for remote attackers to bypass CRL validation by using a nextUpdate value corresponding to a time in the past. (CVE-2011-3207) - OpenSSL 0.9.8s and 1.0.0f does not properly support DTLS applications, which allows remote attackers to cause a denial of service (crash) via unspecified vectors related to an out-of-bounds read. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-4108. (CVE-2012-0050) - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1 before 1.0.1a does not properly interpret integer data, which allows remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. (CVE-2012-2110) - The ssl3_take_mac function in ssl/s3_both.c in OpenSSL 1.0.1 before 1.0.1f allows remote TLS servers to cause a denial of service (NULL pointer dereference and application crash) via a crafted Next Protocol Negotiation record in a TLS handshake. (CVE-2013-4353) - The ssl_get_algorithm2 function in ssl/s3_lib.c in OpenSSL before 1.0.2 obtains a certain version number from an incorrect data structure, which allows remote attackers to cause a denial of service (daemon crash) via crafted traffic from a TLS 1.2 client. (CVE-2013-6449) - The DTLS retransmission implementation in OpenSSL 1.0.0 before 1.0.0l and 1.0.1 before 1.0.1f does not properly maintain data structures for digest and encryption contexts, which might allow man-in-the-middle attackers to trigger the use of a different context and cause a denial of service (application crash) by interfering with packet delivery, related to ssl/d1_both.c and ssl/t1_enc.c. (CVE-2013-6450) - An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. (CVE-2014-0160) - A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining (CBC) mode. This flaw allows a man-in-the-middle (MITM) attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a victim application to repeatedly send the same data over newly created SSL 3.0 connections. (CVE-2014-3566) - A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite.

| description | OpenSSL is a widely used library for SSL and TLS protocol implementation that secures data using encryption and decryption based on cryptographic functions. However, a Security Bypass vulnerability – recently addressed in a patch by the OpenSSL Project –can be exploited to make vulnerable SSL clients or remote SSL servers send clean application data without encryption. This Security Bypass vulnerability (CVE-2017-3737) is caused by an error when the SSL_read or SSL_write function handles an "error state" during an SSL handshake. In this paper the FortiGuard Labs team examines the root cause of this vulnerability. The "error state" mechanism was introduced in OpenSSL beginning with version 1.0.2b, It is used to make OpenSSL move into an error state whenever a fatal error occurs during the SSL handshake that would fail if the SSL handshake continued. If SSL_read or SSL_write function is called directly, it checks the SSL handshake state and performs a new SSL handshake automatically if no handshake has been initiated. If a fatal error occurs during the SSL handshake, OpenSSL moves into the error state and returns an error message to the caller. However, the problem occurs if the caller doesn't check the error state and simply calls the SSL_read or SSL_write function again, because it then sends application data without encryption. The following code snippet was taken from OpenSSL 1.0.2m. (Comments added by me have been highlighted.) `ssl/s3_pkt.c`: ``` 638 int ssl3_write_bytes(SSL *s, int type, const void *buf_, int len) 639 { 640 const unsigned char *buf = buf_; 641 int tot; 642 unsigned int n, nw; 643 #if !defined(OPENSSL_NO_MULTIBLOCK) && EVP_CIPH_FLAG_TLS1_1_MULTIBLOCK 644 unsigned int max_send_fragment; 645 #endif 646 SSL3_BUFFER *wb = &(s->s3->wbuf); 647 int i; 648 649 s->rwstate = SSL_NOTHING; 650 OPENSSL_assert(s->s3->wnum <= INT_MAX); 651 tot = s->s3->wnum; 652 s->s3->wnum = 0; 653 654 if (SSL_in_init(s) && !s->in_handshake) { //checks to see if the SSL handshake state is initiated. The state will be SSL_ST_INIT the first time. 655 i = s->handshake_func(s); //performs a new SSL handshake if no handshake has been initiated. 656 if (i < 0) 657 return (i); 658 if (i == 0) { 659 SSLerr(SSL_F_SSL3_WRITE_BYTES, SSL_R_SSL_HANDSHAKE_FAILURE); 660 return -1; 661 } 662 } ``` ssl3_write_bytes() is called by the SSL_write function to send the application data. It checks the SSL handshake state and performs the SSL handshake if needed. `ssl/s3_clnt.c`: ``` 898 int ssl3_get_server_hello(SSL *s) 899 { 900 STACK_OF(SSL_CIPHER) *sk; 901 const SSL_CIPHER *c; 902 CERT *ct = s->cert; 903 unsigned char *p, *d; 904 int i, al = SSL_AD_INTERNAL_ERROR, ok; .... 1077 if (i < 0) { 1078 /* we did not say we would use this cipher */ 1079 al = SSL_AD_ILLEGAL_PARAMETER; 1080 SSLerr(SSL_F_SSL3_GET_SERVER_HELLO, SSL_R_WRONG_CIPHER_RETURNED); 1081 goto f_err; //a fatal error occurs 1082 } .... 1170 f_err: 1171 ssl3_send_alert(s, SSL3_AL_FATAL, al); //sends an SSL alert packet 1172 err: 1173 s->state = SSL_ST_ERR; //moves into an error state 1174 return (-1); 1175 } ``` We used a vulnerable SSL client as a target during the test. During the SSL handshake it received a malformed server hello message from the SSL server controlled by the attacker. ssl3_get_server_hello() is called to handle this server hello message and a fatal error occurs, causing OpenSSL to move into an error state by setting s->state from SSL_ST_INIT to SSL_ST_ERR. `ssl/s3_pkt.c`: ``` 638 int ssl3_write_bytes(SSL *s, int type, const void *buf_, int len) 639 { 640 const unsigned char *buf = buf_; 641 int tot; 642 unsigned int n, nw; 643 #if !defined(OPENSSL_NO_MULTIBLOCK) && EVP_CIPH_FLAG_TLS1_1_MULTIBLOCK 644 unsigned int max_send_fragment; 645 #endif 646 SSL3_BUFFER *wb = &(s->s3->wbuf); 647 int i; 648 649 s->rwstate = SSL_NOTHING; 650 OPENSSL_assert(s->s3->wnum <= INT_MAX); 651 tot = s->s3->wnum; 652 s->s3->wnum = 0; 653 654 if (SSL_in_init(s) && !s->in_handshake) { // SSL_in_init is called again to check the state ``` If the vulnerable SSL client doesn't check the error state and call SSL_write function to send application data again, ssl3_write_bytes() is called and uses SSL_in_init() to check the handshake state again. `include/openssl/ssl.h`: ``` 1749 # define SSL_in_init(a) (SSL_state(a)&SSL_ST_INIT) //s->state is now SSL_ST_ERR, and check returns are false. ``` This time the check fails, the SSL handshake is bypassed and the application data will be sent without encryption. The following traffic dump shows how the clean application data is sent:  During this attack, the attacker entices the vulnerable SSL client to connect to a malicious SSL server. The SSL client may bypass the handshake process and send the application data without encryption. The SSL server may also have the same vulnerability if SSL_read or SSL_write function is called directly. NOTE: authentication is NOT required to exploit this vulnerability. ##### IPS Signature FortiGuard released IPS signature OpenSSL.Handshake.Error.State.Security.Bypass to address this vulnerability. |
