Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. An invalid pointer use flaw was found in OpenSSL's ASN1_TYPE_cmp() function. A remote attacker could crash a TLS/SSL client or server using OpenSSL via a specially crafted X.509 certificate when the attacker-supplied certificate was verified by the application. (CVE-2015-0286) An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input (such as a PEM file) could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded. (CVE-2015-0292) A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. (CVE-2015-0293) A use-after-free flaw was found in the way OpenSSL imported malformed Elliptic Curve private keys. A specially crafted key file could cause an application using OpenSSL to crash when imported. (CVE-2015-0209) An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash. (CVE-2015-0287) A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate handling implementation. A specially crafted X.509 certificate could cause an application using OpenSSL to crash if the application attempted to convert the certificate to a certificate request. (CVE-2015-0288) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. (CVE-2015-0289) Red Hat would like to thank the OpenSSL project for reporting CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289, CVE-2015-0292, and CVE-2015-0293. Upstream acknowledges Stephen Henson of the OpenSSL development team as the original reporter of CVE-2015-0286, Emilia Käsper of the OpenSSL development team as the original reporter of CVE-2015-0287, Brian Carpenter as the original reporter of CVE-2015-0288, Michal Zalewski of Google as the original reporter of CVE-2015-0289, Robert Dugal and David Ramos as the original reporters of CVE-2015-0292, and Sean Burford of Google and Emilia Käsper of the OpenSSL development team as the original reporters of CVE-2015-0293. This update also fixes the following bug: * When a wrapped Advanced Encryption Standard (AES) key did not require any padding, it was incorrectly padded with 8 bytes, which could lead to data corruption and interoperability problems. With this update, the rounding algorithm in the RFC 5649 key wrapping implementation has been fixed. As a result, the wrapped key conforms to the specification, which prevents the described problems. (BZ#1197667) 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
