The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23, when the Protocols configuration includes h2 or h2c, does not restrict request-header length, which allows remote attackers to cause a denial of service (memory consumption) via crafted CONTINUATION frames in an HTTP/2 request.

The remote host is running a version of macOS that is prior to 10.13. It is, therefore, affected by multiple vulnerabilities in the following components :

 - Apache
 - AppSandbox
 - AppleScript
 - Application Firewall
 - ATS
 - Audio
 - CFNetwork
 - CFNetwork Proxies
 - CFString
 - Captive Network Assistant
 - CoreAudio
 - CoreText
 - DesktopServices
 - Directory Utility
 - file

 - fsck_msdos
 - HFS
 - Heimdal
 - HelpViewer
 - IOFireWireFamily
 - ImageIO

 - WebKit
 - zlib

Note that successful exploitation of the most serious issues can result in arbitrary code execution.

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.25. It is, therefore, affected by the following vulnerabilities :

 - A flaw exists in the mod_session_crypto module due to encryption for data and cookies using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default). An unauthenticated, remote attacker can exploit this, via a padding oracle attack, to decrypt information without knowledge of the encryption key, resulting in the disclosure of potentially sensitive information. (CVE-2016-0736)

 - A denial of service vulnerability exists in the mod_auth_digest module during client entry allocation. An unauthenticated, remote attacker can exploit this, via specially crafted input, to exhaust shared memory resources, resulting in a server crash. (CVE-2016-2161)

 - The Apache HTTP Server is affected by a man-in-the-middle vulnerability known as 'httpoxy' due to a failure to properly resolve namespace conflicts in accordance with RFC 3875 section 4.1.18. The HTTP_PROXY environment variable is set based on untrusted user data in the 'Proxy' header of HTTP requests. The HTTP_PROXY environment variable is used by some web client libraries to specify a remote proxy server. An unauthenticated, remote attacker can exploit this, via a crafted 'Proxy' header in an HTTP request, to redirect an application's internal HTTP traffic to an arbitrary proxy server where it may be observed or manipulated. (CVE-2016-5387)

 - A denial of service vulnerability exists in the mod_http2 module due to improper handling of the LimitRequestFields directive. An unauthenticated, remote attacker can exploit this, via specially crafted CONTINUATION frames in an HTTP/2 request, to inject unlimited request headers into the server, resulting in the exhaustion of memory resources. (CVE-2016-8740)

 - A flaw exists due to improper handling of whitespace patterns in user-agent headers. An unauthenticated, remote attacker can exploit this, via a specially crafted user-agent header, to cause the program to incorrectly process sequences of requests, resulting in interpreting responses incorrectly, polluting the cache, or disclosing the content from one request to a second downstream user-agent. (CVE-2016-8743)

 - A CRLF vulnerability exists in the mod_userdir module. An unauthenticated, remote attacker can exploit this, allowing HTTP response splitting attacks. (CVE-2016-4975)

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

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-2016-5387, CVE-2016-1000102, CVE-2016-1000104)

  - A carry propagation error exists in the     Broadwell-specific Montgomery multiplication procedure     when handling input lengths divisible by but longer than     256 bits. This can result in transient authentication     and key negotiation failures or reproducible erroneous     outcomes of public-key operations with specially crafted     input. A man-in-the-middle attacker can possibly exploit     this issue to compromise ECDH key negotiations that     utilize Brainpool P-512 curves. (CVE-2016-7055)

  - A denial of service vulnerability exists in the     mod_http2 module due to improper handling of the     LimitRequestFields directive. An unauthenticated, remote     attacker can exploit this, via specially crafted     CONTINUATION frames in an HTTP/2 request, to inject     unlimited request headers into the server, resulting in     the exhaustion of memory resources. (CVE-2016-8740)

  - A flaw exists due to improper handling of whitespace     patterns in user-agent headers. An unauthenticated,     remote attacker can exploit this, via a specially     crafted user-agent header, to cause the program to     incorrectly process sequences of requests, resulting in     interpreting responses incorrectly, polluting the cache,     or disclosing the content from one request to a second     downstream user-agent. (CVE-2016-8743)

  - A flaw exits in libcurl in the randit() function within     file lib/rand.c due to improper initialization of the     32-bit random value, which is used, for example, to     generate Digest and NTLM authentication nonces,     resulting in weaker cryptographic operations than     expected. (CVE-2016-9594)

  - A floating pointer exception flaw exists in the     exif_convert_any_to_int() function in exif.c that is     triggered when handling TIFF and JPEG image tags. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition. (CVE-2016-10158)

  - An integer overflow condition exists in the     phar_parse_pharfile() function in phar.c due to improper     validation when handling phar archives. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition. (CVE-2016-10159)

  - An off-by-one overflow condition exists in the     phar_parse_pharfile() function in phar.c due to improper     parsing of phar archives. An unauthenticated, remote     attacker can exploit this to cause a crash, resulting in     a denial of service condition. (CVE-2016-10160)

  - An out-of-bounds read error exists in the     finish_nested_data() function in var_unserializer.c due     to improper validation of unserialized data. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition or the disclosure of memory contents.
    (CVE-2016-10161)

  - A denial of service vulnerability exists in the     gdImageCreateFromGd2Ctx() function within file gd_gd2.c     in the GD Graphics Library (LibGD) when handling images     claiming to contain more image data than they actually     do. An unauthenticated, remote attacker can exploit this     to crash a process linked against the library.
    (CVE-2016-10167)

  - An out-of-bounds read error exists when handling packets     using the CHACHA20/POLY1305 or RC4-MD5 ciphers. An     unauthenticated, remote attacker can exploit this, via     specially crafted truncated packets, to cause a denial     of service condition. (CVE-2017-3731)

  - A carry propagating error exists in the x86_64     Montgomery squaring implementation that may cause the     BN_mod_exp() function to produce incorrect results. An     unauthenticated, remote attacker with sufficient     resources can exploit this to obtain sensitive     information regarding private keys. Note that this issue     is very similar to CVE-2015-3193. Moreover, the attacker     would additionally need online access to an unpatched     system using the target private key in a scenario with     persistent DH parameters and a private key that is     shared between multiple clients. For example, this can     occur by default in OpenSSL DHE based SSL/TLS cipher     suites. (CVE-2017-3732)

  - An out-of-bounds read error exists in the     phar_parse_pharfile() function in phar.c due to improper     parsing of phar archives. An unauthenticated, remote     attacker can exploit this to cause a crash, resulting in     a denial of service condition.

  - Multiple stored cross-site scripting (XSS)     vulnerabilities exist in unspecified scripts due to a     failure to validate input before returning it to users.
    An authenticated, remote authenticated attacker can     exploit these, via a specially crafted request, to     execute arbitrary script code in a user's browser     session.

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

This update for apache2 fixes the following issues :

  - CVE-2016-8740 Server memory can be exhausted and service     denied when HTTP/2 is used [bsc#1013648]

This update was imported from the SUSE:SLE-12-SP2:Update update project.

The version of Apache HTTP Server 2.4.x installed on the remote host is prior to 2.4.25. It is, therefore, affected by multiple vulnerabilities :

mod_http2 reports :

The Apache HTTPD web server (from 2.4.17-2.4.23) did not apply limitations on request headers correctly when experimental module for the HTTP/2 protocol is used to access a resource.

The net result is that a the server allocates too much memory instead of denying the request. This can lead to memory exhaustion of the server by a properly crafted request.
