    descriptionIt was discovered that the elliptic curve cryptography (ECC) subsystem in OpenSSL, when using the Elliptic Curve Digital Signature Algorithm (ECDSA) for the ECDHE_ECDSA cipher suite, did not properly implement curves over binary fields. This could allow an attacker to determine private keys via a timing attack. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-1945) Adam Langley discovered that the ephemeral Elliptic Curve Diffie-Hellman (ECDH) functionality in OpenSSL did not ensure thread safety while processing handshake messages from clients. This could allow a remote attacker to cause a denial of service via out-of-order messages that violate the TLS protocol. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-3210) Nadhem Alfardan and Kenny Paterson discovered that the Datagram Transport Layer Security (DTLS) implementation in OpenSSL performed a MAC check only if certain padding is valid. This could allow a remote attacker to recover plaintext. (CVE-2011-4108) Antonio Martin discovered that a flaw existed in the fix to address CVE-2011-4108, the DTLS MAC check failure. This could allow a remote attacker to cause a denial of service. (CVE-2012-0050) Ben Laurie discovered a double free vulnerability in OpenSSL that could be triggered when the X509_V_FLAG_POLICY_CHECK flag is enabled. This could allow a remote attacker to cause a denial of service. This issue only affected Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04. (CVE-2011-4109) It was discovered that OpenSSL, in certain circumstances involving ECDH or ECDHE cipher suites, used an incorrect modular reduction algorithm in its implementation of the P-256 and P-384 NIST elliptic curves. This could allow a remote attacker to obtain the private key of a TLS server via multiple handshake attempts. This issue only affected Ubuntu 8.04 LTS. (CVE-2011-4354) Adam Langley discovered that the SSL 3.0 implementation in OpenSSL did not properly initialize data structures for block cipher padding. This could allow a remote attacker to obtain sensitive information. (CVE-2011-4576) Andrew Chi discovered that OpenSSL, when RFC 3779 support is enabled, could trigger an assert when handling an X.509 certificate containing certificate-extension data associated with IP address blocks or Autonomous System (AS) identifiers. This could allow a remote attacker to cause a denial of service. (CVE-2011-4577) Adam Langley discovered that the Server Gated Cryptography (SGC) implementation in OpenSSL did not properly handle handshake restarts. This could allow a remote attacker to cause a denial of service. (CVE-2011-4619) Andrey Kulikov discovered that the GOST block cipher engine in OpenSSL did not properly handle invalid parameters. This could allow a remote attacker to cause a denial of service via crafted data from a TLS client. This issue only affected Ubuntu 11.10. (CVE-2012-0027). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe OpenSSL Team reports : 6 security flaws have been fixed in OpenSSL 1.0.0f : If X509_V_FLAG_POLICY_CHECK is set in OpenSSL 0.9.8, then a policy check failure can lead to a double-free. OpenSSL prior to 1.0.0f and 0.9.8s failed to clear the bytes used as block cipher padding in SSL 3.0 records. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could include sensitive contents of previously freed memory. RFC 3779 data can be included in certificates, and if it is malformed, may trigger an assertion failure. This could be used in a denial-of-service attack. Support for handshake restarts for server gated cryptograpy (SGC) can be used in a denial-of-service attack. A malicious TLS client can send an invalid set of GOST parameters which will cause the server to crash due to lack of error checking. This could be used in a denial-of-service attack.

    NASL idMANDRIVA_MDVSA-2012-007.NASL
    descriptionMultiple vulnerabilities has been found and corrected in openssl : The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack (CVE-2011-4108). Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to have an unspecified impact by triggering failure of a policy check (CVE-2011-4109). The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer (CVE-2011-4576). The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service via unspecified vectors (CVE-2011-4619). The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remote attackers to cause a denial of service (daemon crash) via crafted data from a TLS client (CVE-2012-0027). The updated packages have been patched to correct these issues.

  • NASL familySolaris Local Security Checks
    NASL idSOLARIS11_OPENSSL_20120404.NASL
    descriptionThe remote Solaris system is missing necessary patches to address security updates : - The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack. (CVE-2011-4108) - Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to have an unspecified impact by triggering failure of a policy check.

(CVE-2011-4576) - OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers. (CVE-2011-4577) - The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors. (CVE-2011-4619) - The GOST ENGINE in OpenSSL before 1.0.0f does not properly handle invalid parameters for the GOST block cipher, which allows remote attackers to cause a denial of service (daemon crash) via crafted data from a TLS client. (CVE-2012-0027) - OpenSSL 0.9.8s and 1.0.0f does not properly support DTLS applications, which allows remote attackers to cause a denial of service (crash) via unspecified vectors related to an out-of-bounds read. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-4108. (CVE-2012-0050)

  • NASL familyGentoo Local Security Checks
    NASL idGENTOO_GLSA-201203-12.NASL
    descriptionThe remote host is affected by the vulnerability described in GLSA-201203-12 (OpenSSL: Multiple vulnerabilities) Multiple vulnerabilities have been found in OpenSSL: Timing differences for decryption are exposed by CBC mode encryption in OpenSSL&rsquo;s implementation of DTLS (CVE-2011-4108). A policy check failure can result in a double-free error when X509_V_FLAG_POLICY_CHECK is set (CVE-2011-4109). Clients and servers using SSL 3.0 handshakes do not clear the block cipher padding, allowing a record to contain up to 15 bytes of uninitialized memory, which could include sensitive information (CVE-2011-4576). Assertion errors can occur during the handling of malformed X.509 certificates when OpenSSL is built with RFC 3779 support (CVE-2011-4577). A resource management error can occur when OpenSSL&rsquo;s server gated cryptography (SGC) does not properly handle handshake restarts (CVE-2011-4619). Invalid parameters in the GOST block cipher are not properly handled by the GOST ENGINE(CVE-2012-0027). An incorrect fix for CVE-2011-4108 creates an unspecified vulnerability for DTLS applications using OpenSSL (CVE-2012-0050). Impact : A remote attacker may be able to cause a Denial of Service or obtain sensitive information, including plaintext passwords. Workaround : There is no known workaround at this time.
