CVE-2017-3738

TITLE

OpenSSL Vulnerability in

DESCRIPTION

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. This vulnerability CVE-2017-3736 , CVE-2017-3732 and CVE-2015-3193 Similar problem.It may be affected unspecified. An attacker can exploit this issue to gain access to sensitive information that may aid in further attacks. =========================================================================== Ubuntu Security Notice USN-3512-1 December 11, 2017 openssl vulnerabilities =========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS Summary: Several security issues were fixed in OpenSSL. Software Description: - openssl: Secure Socket Layer (SSL) cryptographic library and tools Details: David Benjamin discovered that OpenSSL did not correctly prevent buggy applications that ignore handshake errors from subsequently calling certain functions. While unlikely, a remote attacker could possibly use this issue to recover private keys. (CVE-2017-3738) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: libssl1.0.0 1.0.2g-1ubuntu13.3 Ubuntu 17.04: libssl1.0.0 1.0.2g-1ubuntu11.4 Ubuntu 16.04 LTS: libssl1.0.0 1.0.2g-1ubuntu4.10 After a standard system update you need to reboot your computer to make all the necessary changes. Corrected: 2017-12-07 18:04:48 UTC (stable/11, 11.1-STABLE) 2017-12-09 03:44:26 UTC (releng/11.1, 11.1-RELEASE-p6) 2017-12-09 03:41:31 UTC (stable/10, 10.4-STABLE) 2017-12-09 03:45:23 UTC (releng/10.4, 10.4-RELEASE-p5) 2017-12-09 03:45:23 UTC (releng/10.3, 10.3-RELEASE-p26) CVE Name: CVE-2017-3737, CVE-2017-3738 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. Background FreeBSD includes software from the OpenSSL Project. It is also a full-strength general purpose cryptography library. II. Problem Description Invoking SSL_read()/SSL_write() while in an error state causes data to be 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. [CVE-2017-3738] This bug only affects FreeBSD 11.x. III. 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. [CVE-2017-3738] 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. [FreeBSD 10.x] # fetch https://security.FreeBSD.org/patches/SA-17:12/openssl-10.patch # fetch https://security.FreeBSD.org/patches/SA-17:12/openssl-10.patch.asc # gpg --verify openssl-10.patch.asc [FreeBSD 11.x] # fetch https://security.FreeBSD.org/patches/SA-17:12/openssl-11.patch # fetch https://security.FreeBSD.org/patches/SA-17:12/openssl-11.patch.asc # gpg --verify openssl-11.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>. Restart all daemons that use the library, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch. Branch/path Revision - ------------------------------------------------------------------------- stable/10/ r326721 releng/10.3/ r326723 releng/10.4/ r326723 stable/11/ r326663 releng/11.1/ r326722 - ------------------------------------------------------------------------- To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: <URL:https://svnweb.freebsd.org/base?view=revision&revision=NNNNNN> VII. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security and bug fix update Advisory ID: RHSA-2018:0998-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:0998 Issue date: 2018-04-10 CVE Names: CVE-2017-3736 CVE-2017-3737 CVE-2017-3738 ===================================================================== 1.

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. 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. 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. 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.
