TITLE

OpenSSL CVE-2016-2105 Buffer Overflow Vulnerability

DESCRIPTION

Integer overflow in the EVP_EncodeUpdate function in crypto/evp/encode.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of binary data. OpenSSL is prone to a buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.. Attackers can exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will result in denial-of-service conditions. Following product versions are affected: OpenSSL versions 1.0.2 prior to 1.0.2h OpenSSL versions 1.0.1 prior to 1.0.1t. It supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, security hashing algorithm, etc. Corrected: 2016-05-03 18:54:20 UTC (stable/10, 10.3-STABLE) 2016-05-04 15:25:47 UTC (releng/10.3, 10.3-RELEASE-p2) 2016-05-04 15:26:23 UTC (releng/10.2, 10.2-RELEASE-p16) 2016-05-04 15:27:09 UTC (releng/10.1, 10.1-RELEASE-p33) 2016-05-04 06:53:02 UTC (stable/9, 9.3-STABLE) 2016-05-04 15:27:09 UTC (releng/9.3, 9.3-RELEASE-p41) CVE Name: CVE-2016-2105, CVE-2016-2106, CVE-2016-2107, CVE-2016-2109, CVE-2016-2176 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. II. Problem Description The padding check in AES-NI CBC MAC was rewritten to be in constant time by making sure that always the same bytes are read and compared against either the MAC or padding bytes. But it no longer checked that there was enough data to have both the MAC and padding bytes. [CVE-2016-2107] An overflow can occur in the EVP_EncodeUpdate() function which is used for Base64 encoding of binary data. [CVE-2016-2105] An overflow can occur in the EVP_EncryptUpdate() function, however it is believed that there can be no overflows in internal code due to this problem. [CVE-2016-2106] When ASN.1 data is read from a BIO using functions such as d2i_CMS_bio() a short invalid encoding can casuse allocation of large amounts of memory potentially consuming excessive resources or exhausting memory. [CVE-2016-2109] ASN1 Strings that are over 1024 bytes can cause an overread in applications using the X509_NAME_oneline() function on EBCDIC systems. [CVE-2016-2176] FreeBSD does not run on any EBCDIC systems and therefore is not affected. III. [CVE-2016-2109] TLS applications are not affected. 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-16:17/openssl-10.patch # fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-10.patch.asc # gpg --verify openssl-10.patch.asc [FreeBSD 9.3] # fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-9.patc # fetch https://security.FreeBSD.org/patches/SA-16:17/openssl-9.patch.asc # gpg --verify openssl-9.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.

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. Security Fix(es): * A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2105, CVE-2016-2106) * It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2016-2107) * Several flaws were found in the way BIO_*printf functions were implemented in OpenSSL. Applications which passed large amounts of untrusted data through these functions could crash or potentially execute code with the permissions of the user running such an application. (CVE-2016-0799, CVE-2016-2842) * A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. An application using OpenSSL that accepts untrusted ASN.1 BIO input could be forced to allocate an excessive amount of data. (CVE-2016-2109) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-2108, CVE-2016-2842, CVE-2016-2105, CVE-2016-2106, CVE-2016-2107, and CVE-2016-0799.

Description: Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. This release includes bug fixes and enhancements, as well as a new release of OpenSSL that addresses a number of outstanding security flaws. For further information, see the knowledge base article linked to in the References section. (CVE-2016-2108) * Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. (CVE-2015-3195) * A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange (for both export and non-export grade cipher suites). An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. (CVE-2016-2106) * It was discovered that it is possible to remotely Segfault Apache http server with a specially crafted string sent to the mod_cluster via service messages (MCMP). (CVE-2016-2109) * It was discovered that specifying configuration with a JVMRoute path longer than 80 characters will cause segmentation fault leading to a server crash.

(CVE-2016-5419, CVE-2016-5420, CVE-2016-7141) * This update fixes two flaws in httpd. (CVE-2014-3523, CVE-2015-3185) * This update fixes two flaws in mod_cluster. (CVE-2016-4459, CVE-2016-8612) * A buffer overflow flaw when concatenating virtual host names and URIs was fixed in mod_jk. (CVE-2016-6808) * A memory leak flaw was fixed in expat. After installing the updated packages, the httpd daemon will be restarted automatically.
