TITLE

OpenSSL of crypto/x509/x509_vfy.c of X509_cmp_time Service disruption in functions (DoS) Vulnerabilities

DESCRIPTION

The X509_cmp_time function in crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback. OpenSSL is prone to denial-of-service vulnerability. An attacker may exploit this issue to cause a denial-of-service condition. The following are vulnerable: OpenSSL 1.0.2 prior to 1.0.2b OpenSSL 1.0.1 prior to 1.0.1n OpenSSL 1.0.0 prior to 1.0.0s OpenSSL 0.9.8 prior to 0.9.8zg. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20564.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_n a-c05157667 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c05157667 Version: 1 HPSBMU03607 rev.1 - HPE BladeSystem c-Class Virtual Connect (VC) Firmware, Remote Denial of Service (DoS), Disclosure of Information, Cross-Site Request Forgery (CSRF) NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Corrected: 2015-06-11 19:07:45 UTC (stable/10, 10.1-STABLE) 2015-06-12 07:23:55 UTC (releng/10.1, 10.1-RELEASE-p12) 2015-06-11 19:39:27 UTC (stable/9, 9.3-STABLE) 2015-06-12 07:23:55 UTC (releng/9.3, 9.3-RELEASE-p16) 2015-06-11 19:39:27 UTC (stable/8, 8.4-STABLE) 2015-06-12 07:23:55 UTC (releng/8.4, 8.4-RELEASE-p30) CVE Name: CVE-2015-1788, CVE-2015-1789, CVE-2015-1790, CVE-2015-1791 CVE-2015-1792, CVE-2015-4000 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/>. 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 A vulnerability in the TLS protocol would allow a man-in-the-middle attacker to downgrade vulnerable TLS connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. This vulnerability is also known as Logjam [CVE-2015-4000]. When processing an ECParameters structure OpenSSL enters an infinite loop if the curve specified is over a specially malformed binary polynomial field. [CVE-2015-1788] X509_cmp_time does not properly check the length of the ASN1_TIME string and can read a few bytes out of bounds. In addition, X509_cmp_time accepts an arbitrary number of fractional seconds in the time string. [CVE-2015-1789] The PKCS#7 parsing code does not handle missing inner EncryptedContent correctly. [CVE-2015-1790] When verifying a signedData message the CMS code can enter an infinite loop if presented with an unknown hash function OID. [CVE-2015-1792] If a NewSessionTicket is received by a multi-threaded client when attempting to reuse a previous ticket then a race condition can occur, potentially leading to a double free of the ticket data. [CVE-2015-1791] The OpenSSL advisory also describes a problem that is identified as CVE-2014-8176, which is already fixed by an earlier FreeBSD Errata Notice, FreeBSD-EN-15:02.openssl. III. Impact A man-in-the-middle attacker may be able to downgrade vulnerable TLS connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. [CVE-2015-4000]. On FreeBSD 10.1, the patch contains a countermeasure for clients by rejecting handshakes with DH parameters shorter than 768 bits. An attacker who is able to use a certificate to authenticate with a remote system perform denial of service against any system which processes public keys, certificate requests or certificates. [CVE-2015-1788]. This affects FreeBSD 10.1 only, as the problem was no longer exist in OpenSSL 0.9.8 series since July 2012. An attacker can use the CVE-2015-1789 issue by using specifically crafted certificates and CRLs of various sizes and potentially cause a segmentation fault, resulting in a DoS on applications that verify certificates or CRLs. An attacker who can create specifically crafted malformed ASN.1-encoded PKCS#7 blobs with missing content and trigger a NULL pointer dereference on parsing. [CVE-2015-1790]. Applications that decrypt PKCS#7 data or otherwise parse PKCS#7 structures from untrusted sources are affected. OpenSSL clients and servers are not affected. An attacker can perform denial of service against any system which verifies signedData messages using the CMS code. [CVE-2015-1792] An attacker may be able to crash multi-thread applications that supports resumed TLS handshakes. [CVE-2015-1791] 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. 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 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 10.1] # fetch https://security.FreeBSD.org/patches/SA-15:10/openssl-10.1.patch # fetch https://security.FreeBSD.org/patches/SA-15:10/openssl-10.1.patch.asc # gpg --verify openssl-10.1.patch.asc [FreeBSD 9.3 and 8.4] # fetch https://security.FreeBSD.org/patches/SA-15:10/openssl-8.4.patch # fetch https://security.FreeBSD.org/patches/SA-15:10/openssl-8.4.patch.asc # gpg --verify openssl-8.4.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 deamons using the library, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL. A specially crafted X.509 certificate or a Certificate Revocation List (CRL) could possibly cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2015-1789) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. A specially crafted PKCS#7 input with missing EncryptedContent data could cause an application using OpenSSL to crash. (CVE-2015-1790) A flaw was found in the way the TLS protocol composes the Diffie-Hellman (DH) key exchange. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenSSL to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Future updates may raise this limit to 1024 bits. Red Hat would like to thank the OpenSSL project for reporting CVE-2015-1789 and CVE-2015-1790. Upstream acknowledges Robert Swiecki and Hanno Böck as the original reporters of CVE-2015-1789, and Michal Zalewski as the original reporter of CVE-2015-1790. All openssl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1223211 - CVE-2015-4000 LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks 1228603 - CVE-2015-1789 OpenSSL: out-of-bounds read in X509_cmp_time 1228604 - CVE-2015-1790 OpenSSL: PKCS7 crash with missing EnvelopedContent 6.
