TITLE

OpenSSL of crypto/evp/encode.c of EVP_EncodeUpdate Integer overflow vulnerability in functions

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. It supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, security hashing algorithm, etc. ============================================================================ Ubuntu Security Notice USN-2959-1 May 03, 2016 openssl vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 15.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in OpenSSL. (CVE-2016-2106) Brian Carpenter discovered that OpenSSL incorrectly handled memory when ASN.1 data is read from a BIO. (CVE-2016-2109) As a security improvement, this update also modifies OpenSSL behaviour to reject DH key sizes below 1024 bits, preventing a possible downgrade attack. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 LTS: libssl1.0.0 1.0.2g-1ubuntu4.1 Ubuntu 15.10: libssl1.0.0 1.0.2d-0ubuntu1.5 Ubuntu 14.04 LTS: libssl1.0.0 1.0.1f-1ubuntu2.19 Ubuntu 12.04 LTS: libssl1.0.0 1.0.1-4ubuntu5.36 After a standard system update you need to reboot your computer to make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Enterprise Application Platform 6.4.10 natives update on RHEL 7 Advisory ID: RHSA-2016:2054-01 Product: Red Hat JBoss Enterprise Application Platform Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2054.html Issue date: 2016-10-12 CVE Names: CVE-2015-3183 CVE-2015-3195 CVE-2015-4000 CVE-2016-2105 CVE-2016-2106 CVE-2016-2108 CVE-2016-2109 CVE-2016-3110 CVE-2016-4459 ===================================================================== 1. Summary: Updated packages that provide Red Hat JBoss Enterprise Application Platform 6.4.10 natives, fix several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat JBoss Enterprise Application Platform 6.4 for RHEL 7 Server - noarch, ppc64, x86_64 3. 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. All users of Red Hat JBoss Enterprise Application Platform 6.4 on Red Hat Enterprise Linux 7 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect. 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-2016-2108) * 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-2015-3183) * A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. (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. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. A remote attacker could use this flaw to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (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-2016-3110) * 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) * It was discovered that specifying configuration with a JVMRoute path longer than 80 characters will cause segmentation fault leading to a server crash. (CVE-2016-4459) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-2108, CVE-2016-2105, and CVE-2016-2106 and Michal Karm Babacek for reporting CVE-2016-3110. The CVE-2016-4459 issue was discovered by Robert Bost (Red Hat). Upstream acknowledges Huzaifa Sidhpurwala (Red Hat), Hanno BAPck, and David Benjamin (Google) as the original reporters of CVE-2016-2108; and Guido Vranken as the original reporter of CVE-2016-2105 and CVE-2016-2106. 4. Solution: Before applying this update, back up your existing Red Hat JBoss Enterprise Application Platform installation and deployed applications. 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.
