The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division results, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via unknown vectors. ( Out-of-bounds writes and application crashes ) There are vulnerabilities that are subject to unspecified impact, such as being put into a state. Supplementary information : CWE Vulnerability type by CWE-787: Out-of-bounds Write ( Out-of-bounds writing ) Has been identified. http://cwe.mitre.org/data/definitions/787.htmlService disruption by a third party ( Out-of-bounds writes and application crashes ) There is a possibility of being affected unspecified, such as being in a state. OpenSSL is prone to denial-of-service vulnerability. An attacker may exploit this issue to crash the affected application, resulting in denial-of-service condition. OpenSSL Security Advisory [22 Sep 2016] ======================================== OCSP Status Request extension unbounded memory growth (CVE-2016-6304) ===================================================================== Severity: High A malicious client can send an excessively large OCSP Status Request extension. If that client continually requests renegotiation, sending a large OCSP Status Request extension each time, then there will be unbounded memory growth on the server. This will eventually lead to a Denial Of Service attack through memory exhaustion. Servers with a default configuration are vulnerable even if they do not support OCSP. Builds using the "no-ocsp" build time option are not affected. Servers using OpenSSL versions prior to 1.0.1g are not vulnerable in a default configuration, instead only if an application explicitly enables OCSP stapling support. OpenSSL 1.1.0 users should upgrade to 1.1.0a OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 29th August 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Matt Caswell of the OpenSSL development team. SSL_peek() hang on empty record (CVE-2016-6305) =============================================== Severity: Moderate OpenSSL 1.1.0 SSL/TLS will hang during a call to SSL_peek() if the peer sends an empty record. This could be exploited by a malicious peer in a Denial Of Service attack. OpenSSL 1.1.0 users should upgrade to 1.1.0a This issue was reported to OpenSSL on 10th September 2016 by Alex Gaynor. The fix was developed by Matt Caswell of the OpenSSL development team. SWEET32 Mitigation (CVE-2016-2183) ================================== Severity: Low SWEET32 (https://sweet32.info) is an attack on older block cipher algorithms that use a block size of 64 bits. In mitigation for the SWEET32 attack DES based ciphersuites have been moved from the HIGH cipherstring group to MEDIUM in OpenSSL 1.0.1 and OpenSSL 1.0.2. OpenSSL 1.1.0 since release has had these ciphersuites disabled by default. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 16th August 2016 by Karthikeyan Bhargavan and Gaetan Leurent (INRIA). The fix was developed by Rich Salz of the OpenSSL development team. OOB write in MDC2_Update() (CVE-2016-6303) ========================================== Severity: Low An overflow can occur in MDC2_Update() either if called directly or through the EVP_DigestUpdate() function using MDC2. If an attacker is able to supply very large amounts of input data after a previous call to EVP_EncryptUpdate() with a partial block then a length check can overflow resulting in a heap corruption. The amount of data needed is comparable to SIZE_MAX which is impractical on most platforms. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 11th August 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Stephen Henson of the OpenSSL development team. Malformed SHA512 ticket DoS (CVE-2016-6302) =========================================== Severity: Low If a server uses SHA512 for TLS session ticket HMAC it is vulnerable to a DoS attack where a malformed ticket will result in an OOB read which will ultimately crash. The use of SHA512 in TLS session tickets is comparatively rare as it requires a custom server callback and ticket lookup mechanism. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 19th August 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Stephen Henson of the OpenSSL development team. OOB write in BN_bn2dec() (CVE-2016-2182) ======================================== Severity: Low The function BN_bn2dec() does not check the return value of BN_div_word(). This can cause an OOB write if an application uses this function with an overly large BIGNUM. This could be a problem if an overly large certificate or CRL is printed out from an untrusted source. TLS is not affected because record limits will reject an oversized certificate before it is parsed. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 2nd August 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Stephen Henson of the OpenSSL development team. OOB read in TS_OBJ_print_bio() (CVE-2016-2180) ============================================== Severity: Low The function TS_OBJ_print_bio() misuses OBJ_obj2txt(): the return value is the total length the OID text representation would use and not the amount of data written. This will result in OOB reads when large OIDs are presented. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 21st July 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Stephen Henson of the OpenSSL development team. Pointer arithmetic undefined behaviour (CVE-2016-2177) ====================================================== Severity: Low Avoid some undefined pointer arithmetic A common idiom in the codebase is to check limits in the following manner: "p + len > limit" Where "p" points to some malloc'd data of SIZE bytes and limit == p + SIZE "len" here could be from some externally supplied data (e.g. from a TLS message). The rules of C pointer arithmetic are such that "p + len" is only well defined where len <= SIZE. Therefore the above idiom is actually undefined behaviour. For example this could cause problems if some malloc implementation provides an address for "p" such that "p + len" actually overflows for values of len that are too big and therefore p + len < limit. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 4th May 2016 by Guido Vranken. The fix was developed by Matt Caswell of the OpenSSL development team. Constant time flag not preserved in DSA signing (CVE-2016-2178) =============================================================== Severity: Low Operations in the DSA signing algorithm should run in constant time in order to avoid side channel attacks. A flaw in the OpenSSL DSA implementation means that a non-constant time codepath is followed for certain operations. This has been demonstrated through a cache-timing attack to be sufficient for an attacker to recover the private DSA key. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 23rd May 2016 by César Pereida (Aalto University), Billy Brumley (Tampere University of Technology), and Yuval Yarom (The University of Adelaide and NICTA). The fix was developed by César Pereida. DTLS buffered message DoS (CVE-2016-2179) ========================================= Severity: Low In a DTLS connection where handshake messages are delivered out-of-order those messages that OpenSSL is not yet ready to process will be buffered for later use. Under certain circumstances, a flaw in the logic means that those messages do not get removed from the buffer even though the handshake has been completed. An attacker could force up to approx. 15 messages to remain in the buffer when they are no longer required. These messages will be cleared when the DTLS connection is closed. The default maximum size for a message is 100k. Therefore the attacker could force an additional 1500k to be consumed per connection. By opening many simulataneous connections an attacker could cause a DoS attack through memory exhaustion. OpenSSL 1.0.2 DTLS users should upgrade to 1.0.2i OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1u This issue was reported to OpenSSL on 22nd June 2016 by Quan Luo. The fix was developed by Matt Caswell of the OpenSSL development team. DTLS replay protection DoS (CVE-2016-2181) ========================================== Severity: Low A flaw in the DTLS replay attack protection mechanism means that records that arrive for future epochs update the replay protection "window" before the MAC for the record has been validated. This could be exploited by an attacker by sending a record for the next epoch (which does not have to decrypt or have a valid MAC), with a very large sequence number. This means that all subsequent legitimate packets are dropped causing a denial of service for a specific DTLS connection. OpenSSL 1.0.2 DTLS users should upgrade to 1.0.2i OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1u This issue was reported to OpenSSL on 21st November 2015 by the OCAP audit team. The fix was developed by Matt Caswell of the OpenSSL development team. Certificate message OOB reads (CVE-2016-6306) ============================================= Severity: Low In OpenSSL 1.0.2 and earlier some missing message length checks can result in OOB reads of up to 2 bytes beyond an allocated buffer. There is a theoretical DoS risk but this has not been observed in practice on common platforms. The messages affected are client certificate, client certificate request and server certificate. As a result the attack can only be performed against a client or a server which enables client authentication. OpenSSL 1.1.0 is not affected. OpenSSL 1.0.2 users should upgrade to 1.0.2i OpenSSL 1.0.1 users should upgrade to 1.0.1u This issue was reported to OpenSSL on 22nd August 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Stephen Henson of the OpenSSL development team. Excessive allocation of memory in tls_get_message_header() (CVE-2016-6307) ========================================================================== Severity: Low A TLS message includes 3 bytes for its length in the header for the message. This would allow for messages up to 16Mb in length. Messages of this length are excessive and OpenSSL includes a check to ensure that a peer is sending reasonably sized messages in order to avoid too much memory being consumed to service a connection. A flaw in the logic of version 1.1.0 means that memory for the message is allocated too early, prior to the excessive message length check. Due to way memory is allocated in OpenSSL this could mean an attacker could force up to 21Mb to be allocated to service a connection. This could lead to a Denial of Service through memory exhaustion. However, the excessive message length check still takes place, and this would cause the connection to immediately fail. Assuming that the application calls SSL_free() on the failed conneciton in a timely manner then the 21Mb of allocated memory will then be immediately freed again. Therefore the excessive memory allocation will be transitory in nature. This then means that there is only a security impact if: 1) The application does not call SSL_free() in a timely manner in the event that the connection fails or 2) The application is working in a constrained environment where there is very little free memory or 3) The attacker initiates multiple connection attempts such that there are multiple connections in a state where memory has been allocated for the connection; SSL_free() has not yet been called; and there is insufficient memory to service the multiple requests. Except in the instance of (1) above any Denial Of Service is likely to be transitory because as soon as the connection fails the memory is subsequently freed again in the SSL_free() call. However there is an increased risk during this period of application crashes due to the lack of memory - which would then mean a more serious Denial of Service. This issue does not affect DTLS users. OpenSSL 1.1.0 TLS users should upgrade to 1.1.0a This issue was reported to OpenSSL on 18th September 2016 by Shi Lei (Gear Team, Qihoo 360 Inc.). The fix was developed by Matt Caswell of the OpenSSL development team. Excessive allocation of memory in dtls1_preprocess_fragment() (CVE-2016-6308) ============================================================================= Severity: Low This issue is very similar to CVE-2016-6307. The underlying defect is different but the security analysis and impacts are the same except that it impacts DTLS. A DTLS message includes 3 bytes for its length in the header for the message. This would allow for messages up to 16Mb in length. Messages of this length are excessive and OpenSSL includes a check to ensure that a peer is sending reasonably sized messages in order to avoid too much memory being consumed to service a connection. A flaw in the logic of version 1.1.0 means that memory for the message is allocated too early, prior to the excessive message length check. Due to way memory is allocated in OpenSSL this could mean an attacker could force up to 21Mb to be allocated to service a connection. This could lead to a Denial of Service through memory exhaustion.

The fix was developed by Matt Caswell of the OpenSSL development team.

Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-2178) * It was discovered that the Datagram TLS (DTLS) implementation could fail to release memory in certain cases. A malicious DTLS client could cause a DTLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory. A remote attacker could possibly use this flaw to make a DTLS server using OpenSSL to reject further packets sent from a DTLS client over an established DTLS connection. (CVE-2016-2181) * An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function. (CVE-2016-2182) * A flaw was found in 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. (CVE-2016-2183) This update mitigates the CVE-2016-2183 issue by lowering priority of DES cipher suites so they are not preferred over cipher suites using AES. For compatibility reasons, DES cipher suites remain enabled by default and included in the set of cipher suites identified by the HIGH cipher string. Future updates may move them to MEDIUM or not enable them by default. * An integer underflow flaw leading to a buffer over-read was found in the way OpenSSL parsed TLS session tickets. (CVE-2016-6302) * Multiple integer overflow flaws were found in the way OpenSSL performed pointer arithmetic. A remote attacker could possibly use these flaws to cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2016-2177) * An out of bounds read flaw was found in the way OpenSSL formatted Public Key Infrastructure Time-Stamp Protocol data for printing. A remote attacker could possibly use these flaws to crash a TLS/SSL server or client using OpenSSL. (CVE-2016-6306) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and CVE-2016-6306 and OpenVPN for reporting CVE-2016-2183. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. 5.
