TITLE

OpenSSL Service disruption in (DoS) Vulnerabilities

DESCRIPTION

There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. 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. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem. OpenSSL There is a service disruption ( crash ) There are vulnerabilities that are put into a state.Service operation interruption ( crash ) There is a possibility of being put into a state. OpenSSL is prone to an information-disclosure vulnerability. An attacker can exploit this issue to gain access to sensitive information that may aid in further attacks. Versions prior to OpenSSL 1.1.0d and 1.0.2k are vulnerable. OpenSSL Security Advisory [07 Dec 2017] ======================================== Read/write after SSL object in error state (CVE-2017-3737) ========================================================== Severity: Moderate 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 1.0.2 users should upgrade to 1.0.2n This issue was reported to OpenSSL on 10th November 2017 by David Benjamin (Google). The fix was proposed by David Benjamin and implemented by Matt Caswell of the OpenSSL development team. rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738) ========================================================= Severity: Low There is an overflow bug in the AVX2 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). 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. OpenSSL 1.0.2 users should upgrade to 1.0.2n This issue was reported to OpenSSL on 22nd November 2017 by David Benjamin (Google). The issue was originally found via the OSS-Fuzz project. The fix was developed by Andy Polyakov of the OpenSSL development team. Note ==== Support for version 1.0.1 ended on 31st December 2016. Support for versions 0.9.8 and 1.0.0 ended on 31st December 2015. Those versions are no longer receiving security updates.

I. Background FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. II. Problem Description If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. [CVE-2017-3732] Montgomery multiplication may produce incorrect results. [CVE-2016-7055] III. Impact A remote attacker may trigger a crash on servers or clients that supported RC4-MD5. [CVE-2017-3732, CVE-2016-7055] IV. Workaround No workaround is available. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Restart all daemons that use the library, or reboot the system. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install Restart all daemons that use the library, or reboot the system. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as other releases were fixed in a previous security update. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2016-7055) It was discovered that OpenSSL did not properly use constant-time operations when performing ECDSA P-256 signing. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-7056) Shi Lei discovered that OpenSSL incorrectly handled certain warning alerts. A remote attacker could possibly use this issue to cause OpenSSL to stop responding, resulting in a denial of service. (CVE-2016-8610) Robert =C5=9Awi=C4=99cki discovered that OpenSSL incorrectly handled certain truncated packets. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10.
