Cesar Pereida Garcia reports :

The signing function in crypto/ecdsa/ecdsa_ossl.c in certain OpenSSL versions and forks is vulnerable to timing attacks when signing with the standardized elliptic curve P-256 despite featuring constant-time curve operations and modular inversion. A software defect omits setting the BN_FLG_CONSTTIME flag for nonces, failing to take a secure code path in the BN_mod_inverse method and therefore resulting in a cache-timing attack vulnerability. A malicious user with local access can recover ECDSA P-256 private keys.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3181-1 advisory.

    Guido Vranken discovered that OpenSSL used undefined behaviour when performing pointer arithmetic. A     remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service.
    This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS as other releases were fixed in a     previous security update. (CVE-2016-2177)

    It was discovered that OpenSSL did not properly handle Montgomery multiplication, resulting in incorrect     results leading to transient failures. This issue only applied to Ubuntu 16.04 LTS, and Ubuntu 16.10.
    (CVE-2016-7055)

    It was discovered that OpenSSL did not properly use constant-time operations when performing ECDSA P-256     signing. A remote attacker could possibly use this issue to perform a timing attack and recover private     ECDSA keys. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-7056)

    Shi Lei discovered that OpenSSL incorrectly handled certain warning alerts. A remote attacker could     possibly use this issue to cause OpenSSL to stop responding, resulting in a denial of service.
    (CVE-2016-8610)

    Robert wicki discovered that OpenSSL incorrectly handled certain truncated packets. A remote attacker     could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. (CVE-2017-3731)

    It was discovered that OpenSSL incorrectly performed the x86_64 Montgomery squaring procedure. While     unlikely, a remote attacker could possibly use this issue to recover private keys. This issue only applied     to Ubuntu 16.04 LTS, and Ubuntu 16.10. (CVE-2017-3732)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

These non-security issues were fixed :

  - Detect zero-length encrypted session data early

  - Curve25519 Key Exchange support.

  - Support for alternate chains for certificate     verification.

  - Added EVP interface for MD5+SHA1 hashes

  - Fixed DTLS client failures when the server sends a     certificate request.

  - Corrected handling of padding when upgrading an SSLv2     challenge into an SSLv3/TLS connection. 

  - Allowed protocols and ciphers to be set on a TLS config     object in libtls.

For additional changes please refer to the changelog.

Several vulnerabilities were discovered in OpenSSL :

CVE-2016-7056

A local timing attack was discovered against ECDSA P-256.

CVE-2016-8610

It was discovered that no limit was imposed on alert packets during an SSL handshake.

CVE-2017-3731

Robert Swiecki discovered that the RC4-MD5 cipher when running on 32 bit systems could be forced into an out-of-bounds read, resulting in denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0.1t-1+deb7u2.

We recommend that you upgrade your openssl packages.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1414 advisory.

    Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This     software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged     under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent     update experience.

    This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.23 Service Pack 1 serves as a     replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.23, and includes bug fixes, which are     documented in the Release Notes document linked to in the References.

    Security Fix(es):

    * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session     renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of     memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling     support. (CVE-2016-6304)

    * It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify     integrity of the encrypted session data stored in the user's browser. A remote attacker could use this     flaw to decrypt and modify session data using a padding oracle attack. (CVE-2016-0736)

    * It was discovered that the mod_auth_digest module of httpd did not properly check for memory allocation     failures. A remote attacker could use this flaw to cause httpd child processes to repeatedly crash if the     server used HTTP digest authentication. (CVE-2016-2161)

    * A timing attack flaw was found in OpenSSL that could allow a malicious user with local access to recover     ECDSA P-256 private keys. (CVE-2016-7056)

    * A denial of service flaw was found in the way the TLS/SSL protocol defined processing of ALERT packets     during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an     excessive amount of CPU and fail to accept connections from other clients. (CVE-2016-8610)

    * It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by     the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in     conjunction with a proxy or backend server that interpreted those characters differently, a remote     attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache     poisoning. (CVE-2016-8743)

    * A vulnerability was found in httpd's handling of the LimitRequestFields directive in mod_http2,     affecting servers with HTTP/2 enabled. An attacker could send crafted requests with headers larger than     the server's available memory, causing httpd to crash. (CVE-2016-8740)

    Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and Shi Lei (Gear Team of     Qihoo 360 Inc.) for reporting CVE-2016-8610. Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.)     as the original reporter of CVE-2016-6304.
