        "text": "Stronghold 3 contains a number of open source technologies including\nOpenSSL.  Two issues in OpenSSL have recently been discovered:\n\nOpenSSL is a commercial-grade, full-featured, and open source toolkit that\nimplements Secure Sockets Layer (SSL v2/v3) and Transport Layer\nSecurity (TLS v1) protocols.  It also implements a full-strength general \npurpose cryptography library.\n\nResearchers have discovered a timing attack on RSA keys. Applications\nmaking use of OpenSSL are generally vulnerable to such an attack, unless\nRSA blinding has been turned on. OpenSSL does not use RSA blinding by\ndefault and most applications do not enable RSA blinding. \n\nA local or remote attacker could use this attack to obtain the server\u0027s\nprivate key.  This could be done by determining factors using timing\ndifferences on:\n\n(1) The number of extra reductions during Montgomery reduction\n\n(2) The use of different integer multiplication algorithms (\"Karatsuba\" and\nnormal)\n\nIn order for an attack to be successful, an attacker must have good\nnetwork conditions that allow small changes in timing to be reliably\nobserved.\n\nAdditionally, the SSL and TLS components for OpenSSL allow remote attackers\nto perform an unauthorized RSA private key operation via a modified\nBleichenbacher attack. This attack uses a large number of SSL or TLS\nconnections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak\ninformation regarding the relationship between ciphertext and the\nassociated plaintext.  This is also known as the \"Klima-Pokorny-Rosa attack.\"\n\nThese erratum packages contain a patch provided by the OpenSSL group that\nenables RSA blinding by default and protects against\nKlima-Pokorny-Rosa attacks.",

An active attacker may be able to use timing observations\nto distinguish between two different error cases: cipher padding errors and\nMAC verification errors. Over multiple connections this can leak\nsufficient information to make it possible to retrieve the plaintext of a\ncommon, fixed block.\n\nIn order for an attack to be sucessful, an attacker must be able to act as\na man-in-the-middle to intercept and modify multiple connections, which all\ninvolve a common fixed plaintext block (such as a password), and have good\nnetwork conditions that allow small changes in timing to be reliably\nobserved.\n\nResearchers discovered a timing attack on RSA keys.  Applications making\nuse of OpenSSL are generally vulnerable to such an attack, unless RSA\nblinding has been turned on.  OpenSSL does not use RSA blinding by default\nand most applications do not enable RSA blinding.  \n\nA local or remote attacker could use this attack to obtain the server\u0027s\nprivate key by determining factors using timing differences on (1) the\nnumber of extra reductions during Montgomery reduction, and (2) the use of\ndifferent integer multiplication algorithms (\"Karatsuba\" and normal).\n\nIn order for an attack to be sucessful, an attacker must have good\nnetwork conditions allowing small changes in timing to be reliably\nobserved.\n\nAdditionally, the SSL and TLS components for OpenSSL allow remote attackers\nto perform an unauthorized RSA private key operation via a modified\nBleichenbacher attack. This attack uses a large number of SSL or TLS\nconnections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak\ninformation regarding the relationship between ciphertext and the\nassociated plaintext, aka the \"Klima-Pokorny-Rosa attack.\"\n\nThese erratum packages contain patches provided by the OpenSSL group that\nenable RSA blinding by default and protect against the other vulnerabilities.\n\nBecause server applications are affected by these vulnerabilities, users\nare advised to restart all services that use OpenSSL functionality, or\nreboot their systems after installing these updates.",

Applications making\nuse of OpenSSL are generally vulnerable to such an attack, unless RSA\nblinding has been turned on.  OpenSSL does not use RSA blinding by default\nand most applications do not enable RSA blinding.  \n\nA local or remote attacker could use this attack to obtain the server\u0027s\nprivate key by determining factors using timing differences on (1) the\nnumber of extra reductions during Montgomery reduction, and (2) the use of\ndifferent integer multiplication algorithms (\"Karatsuba\" and normal).\n\nIn order for an attack to be sucessful, an attacker must have good\nnetwork conditions that allow small changes in timing to be reliably\nobserved.\n\nAdditionally, the SSL and TLS components for OpenSSL allow remote attackers\nto perform an unauthorized RSA private key operation via a modified\nBleichenbacher attack. This attack uses a large number of SSL or TLS\nconnections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak\ninformation regarding the relationship between ciphertext and the\nassociated plaintext, aka the \"Klima-Pokorny-Rosa attack.\"\n\nThese erratum packages contain a patch provided by the OpenSSL group that\nenables RSA blinding by default and protects against the\n\"Klima-Pokorny-Rosa attack.\"\n\nBecause server applications are affected by these vulnerabilities, users\nare advised to restart all services that use OpenSSL functionality or\nreboot their systems after installing these updates.",

Applications making\nuse of OpenSSL are generally vulnerable to such an attack, unless RSA\nblinding has been turned on. OpenSSL does not use RSA blinding by default\nand most applications do not enable RSA blinding.\n\nA local or remote attacker could use this attack to obtain the server\u0027s\nprivate key by determining factors using timing differences on (1) the\nnumber of extra reductions during Montgomery reduction, and (2) the use of\ndifferent integer multiplication algorithms (Karatsuba and normal).\n\nIn order for an attack to be sucessful, an attacker must have good\nnetwork conditions that allow small changes in timing to be reliably\nobserved.\n\nAdditionally, the SSL and TLS components for OpenSSL allow remote attackers\nto perform an unauthorized RSA private key operation via a modified\nBleichenbacher attack. This attack (also known as the Klima-Pokorny-Rosa\nattack) uses a large number of SSL or TLS connections using PKCS #1 v1.5\npadding to cause OpenSSL to leak information regarding the relationship\nbetween ciphertext and the associated plaintext.\n\nThese erratum packages contain a patch provided by the OpenSSL group that\nenables RSA blinding by default, and protects against the\nKlima-Pokorny-Rosa attack.\n\nBecause server applications are affected by these vulnerabilities, we\nadvise users to restart all services that use OpenSSL functionality or,\nalternatively, reboot their systems after installing these updates.",
