The remote host is running a version of Mac OS X 10.8.5 or 10.9.5 that is missing Security Update 2015-006. It is, therefore, affected by multiple vulnerabilities in the following components :

  - apache
  - apache_mod_php
  - CoreText
  - FontParser
  - Libinfo
  - libxml2
  - OpenSSL
  - perl
  - PostgreSQL
  - QL Office
  - Quartz Composer Framework
  - QuickTime 7
  - SceneKit

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

The fix for CVE-2016-8743 introduced a regression which would segfault apache workers under certain conditions (#858373), an issue similar to previously fixed CVE-2015-0253.

The issue was introduced in DLA-841-1 and the associated 2.2.22-13+deb7u8 package version. For Debian 7 'Wheezy', these problems have been fixed in version 2.2.22-13+deb7u11.

We recommend that you upgrade your apache2 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to its banner, the version of Apache 2.4.x installed on the remote host is prior to 2.4.16. It is, therefore, affected by the following vulnerabilities :

  - A flaw exists in the lua_websocket_read() function in     the 'mod_lua' module due to incorrect handling of     WebSocket PING frames. A remote attacker can exploit     this, by sending a crafted WebSocket PING frame after a     Lua script has called the wsupgrade() function, to crash     a child process, resulting in a denial of service     condition. (CVE-2015-0228)

  - A NULL pointer dereference flaw exists in the     read_request_line() function due to a failure to     initialize the protocol structure member. A remote     attacker can exploit this flaw, on installations that     enable the INCLUDES filter and has an ErrorDocument 400     directive specifying a local URI, by sending a request     that lacks a method, to cause a denial of service     condition. (CVE-2015-0253)

  - A flaw exists in the chunked transfer coding     implementation due to a failure to properly parse chunk     headers. A remote attacker can exploit this to conduct     HTTP request smuggling attacks. (CVE-2015-3183)

  - A flaw exists in the ap_some_auth_required() function     due to a failure to consider that a Require directive     may be associated with an authorization setting rather     than an authentication setting. A remote attacker can     exploit this, if a module that relies on the 2.2 API     behavior exists, to bypass intended access restrictions.
    (CVE-2015-3185)

  - A flaw exists in the RC4 algorithm due to an initial     double-byte bias in the keystream generation. An     attacker can exploit this, via Bayesian analysis that     combines an a priori plaintext distribution with     keystream distribution statistics, to conduct a     plaintext recovery of the ciphertext. Note that RC4     cipher suites are prohibited per RFC 7465. This issue     was fixed in Apache version 2.4.13; however, 2.4.13,     2.4.14, and 2.4.15 were never publicly released.

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

The remote Mac OS X host has a version of OS X Server installed that is prior to 5.0.3. It is, therefore, affected by the following vulnerabilities :

  - A flaw exists in the mod_headers module that allows HTTP     trailers to replace HTTP headers late during request     processing. A remote attacker can exploit this to inject     arbitrary headers. This can also cause some modules to     function incorrectly or appear to function incorrectly.
    (CVE-2013-5704)

  - A privilege escalation vulnerability exists due to the     'make check' command not properly invoking initdb to     specify authentication requirements for a database     cluster to be used for tests. A local attacker can     exploit this issue to gain temporary server access and     elevated privileges. (CVE-2014-0067)

  - A NULL pointer dereference flaw exists in module     mod_cache. A remote attacker, using an empty HTTP     Content-Type header, can exploit this vulnerability to     crash a caching forward proxy configuration, resulting     in a denial of service if using a threaded MPM.
    (CVE-2014-3581)

  - A out-of-bounds memory read flaw exists in module     mod_proxy_fcgi. An attacker, using a remote FastCGI     server to send long response headers, can exploit this     vulnerability to cause a denial of service by causing     a buffer over-read. (CVE-2014-3583)

  - A flaw exists in module mod_lua when handling a     LuaAuthzProvider used in multiple Require directives     with different arguments. An attacker can exploit this     vulnerability to bypass intended access restrictions.
    (CVE-2014-8109)

  - An information disclosure vulnerability exists due to     improper handling of restricted column values in     constraint-violation error messages. An authenticated,     remote attacker can exploit this to gain access to     sensitive information. (CVE-2014-8161)

  - A flaw exists within the Domain Name Service due to an     error in the code used to follow delegations. A remote     attacker, with a maliciously-constructed zone or query,     can cause the service to issue unlimited queries,     resulting in resource exhaustion. (CVE-2014-8500)

  - A flaw exists in the lua_websocket_read() function in     the 'mod_lua' module due to incorrect handling of     WebSocket PING frames. A remote attacker can exploit     this, by sending a crafted WebSocket PING frame after a     Lua script has called the wsupgrade() function, to crash     a child process, resulting in a denial of service     condition. (CVE-2015-0228)

  - Multiple vulnerabilities exist due to several buffer     overflow errors related to the 'to_char' functions. An     authenticated, remote attacker can exploit these issues     to cause a denial of service or arbitrary code     execution. (CVE-2015-0241)

  - Multiple vulnerabilities exist due to several     stack-based buffer overflow errors in various *printf()     functions. The overflows are due to improper validation     of user-supplied input when formatting a floating point     number where the requested precision is greater than     approximately 500. An authenticated, remote attacker     can exploit these issues to cause a denial of service or     arbitrary code execution. (CVE-2015-0242)

  - Multiple vulnerabilities exist due to an overflow     condition in multiple functions in the 'pgcrypto'     extension. The overflows are due to improper validation     of user-supplied input when tracking memory sizes. An     authenticated, remote attacker can exploit these issues     to cause a denial of service or arbitrary code     execution. (CVE-2015-0243)

  - A SQL injection vulnerability exists due to improper     sanitization of user-supplied input when handling     crafted binary data within a command parameter. An     authenticated, remote attacker can exploit this issue     to inject or manipulate SQL queries, allowing the     manipulation or disclosure of arbitrary data.
    (CVE-2015-0244)

  - A NULL pointer dereference flaw exists in the     read_request_line() function due to a failure to     initialize the protocol structure member. A remote     attacker can exploit this flaw, on installations that     enable the INCLUDES filter and has an ErrorDocument 400     directive specifying a local URI, by sending a request     that lacks a method, to cause a denial of service     condition. (CVE-2015-0253)

  - A denial of service vulnerability exists due to an error     relating to DNSSEC validation and the managed-keys     feature. A remote attacker can trigger an incorrect     trust-anchor management scenario in which no key is     ready for use, resulting in an assertion failure and     daemon crash. (CVE-2015-1349)

  - A flaw exists in PostgreSQL client disconnect timeout     expiration that is triggered when a timeout interrupt     is fired partway through the session shutdown sequence.     (CVE-2015-3165)

  - A flaw exists in the printf() functions due to a failure     to check for errors. A remote attacker can use this to     gain access to sensitive information. (CVE-2015-3166)

  - The pgcrypto component in PostgreSQL has multiple error     messages for decryption with an incorrect key. A remote     attacker can use this to recover keys from other     systems. (CVE-2015-3167)

  - A flaw exists in the chunked transfer coding     implementation due to a failure to properly parse chunk     headers. A remote attacker can exploit this to conduct     HTTP request smuggling attacks. (CVE-2015-3183)

  - A flaw exists in the ap_some_auth_required() function     due to a failure to consider that a Require directive     may be associated with an authorization setting rather     than an authentication setting. A remote attacker can     exploit this, if a module that relies on the 2.2 API     behavior exists, to bypass intended access restrictions.
    (CVE-2015-3185)

  - Multiple unspecified XML flaws exist in the Wiki Server     based on Twisted. (CVE-2015-5911)
