リモートホストは、セキュリティ更新プログラムがないバージョンであるMac OS X 10.10.5または10.11.6を実行しています。したがって、複数の脆弱性の影響を受けます。- ECDSAの実装に欠陥がるため、情報漏えいの脆弱性がLibreSSLコンポーネントにあります。この欠陥は、ECDSAのノンス署名でフラグが適切に設定されておらず、一定のタイムコードパスのみが有効であることを示しているときにトリガーされます。認証されていないリモートの攻撃者がこれを悪用し、再度チャンネルのキャッシュタイミング攻撃を行い、モジュラーインバージョン状態シーケンスやECDSAプライベートキーを取得する可能性があります。この脆弱性はMac OS X 10.10.5には影響しません。（CVE-2016-7056）- ユーザー指定の入力が不適切に検証されているため、整数オーバーフロー状態がImageIOコンポーネントにあります。認証されていないリモートの攻撃者がこれを悪用し、特別に細工されたJPEGファイルを開くようユーザーを誘導し、サービス拒否状態または任意のコードの実行を引き起こす可能性があります。（CVE-2017-2432）- 複数のメモリ破損の問題がlibxsltコンポーネントにあるため、認証されていないリモートの攻撃者がサービス拒否状態または任意のコードの実行を引き起こす可能性があります。（CVE-2017-2477）- 整数オーバーフロー状態がtransform.cのxsltAddTextString()関数のlibxsltコンポーネントにあります。認証されていないリモートの攻撃者がこれを悪用し、特別に細工されたファイルを開くようユーザーを誘導して、領域外書き込みを引き起こし、潜在的に任意のコードを実行する可能性があります。（CVE-2017-5029）

An update is now available for Red Hat JBoss Web Server 3.1 for RHEL 6 and Red Hat JBoss Web Server 3.1 for RHEL 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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)

An update is now available for Red Hat JBoss Core Services on RHEL 6.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - openssl: doapr_outch function does not verify that certain memory allocation succeeds (CVE-2016-2842)

  - The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and     1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via     a DTLS hello message in an invalid DTLS handshake. (CVE-2014-0221)

  - The OBJ_obj2txt function in crypto/objects/obj_dat.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n,     and 1.0.1 before 1.0.1i, when pretty printing is used, does not ensure the presence of '\0' characters,     which allows context-dependent attackers to obtain sensitive information from process stack memory by     reading output from X509_name_oneline, X509_name_print_ex, and unspecified other functions.
    (CVE-2014-3508)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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.

  - fix crash in openssl speed (bsc#1000677)

  - fix ca-bundle path (bsc#1022271)
