The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:1801 advisory.

    Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web     applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache     Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library.

    This release of Red Hat JBoss Web Server 3.1 Service Pack 1 serves as a replacement for Red Hat JBoss Web     Server 3.1, and includes bug fixes, which are documented in the Release Notes document linked to in the     References.

    Security Fix(es):

    * It was found that when using remote logging with log4j socket server the log4j server would deserialize     any log event received via TCP or UDP. An attacker could use this flaw to send a specially crafted log     event that, during deserialization, would execute arbitrary code in the context of the logger application.
    (CVE-2017-5645)

    * A vulnerability was discovered in tomcat's handling of pipelined requests when Sendfile was used. If     sendfile processing completed quickly, it was possible for the Processor to be added to the processor     cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

    * A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A     crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of     the custom error page. (CVE-2017-5664)

    * A vulnerability was discovered in tomcat. When running an untrusted application under a SecurityManager     it was possible, under some circumstances, for that application to retain references to the request or     response objects and thereby access and/or modify information associated with another web application.
    (CVE-2017-5648)

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.

This update for libressl to version 2.5.1 fixes the following issues :

These security issues were fixed :

  - CVE-2016-0702: Prevent side channel attack on modular     exponentiation (boo#968050).

  - CVE-2016-7056: Avoid a side-channel cache-timing attack     that can leak the ECDSA private keys when signing     (boo#1019334).

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.
