Mac OS X : OS X Server < 5.0.3 Multiple Vulnerabilities

High Nessus Plugin ID 86066

Synopsis

The remote host is missing a security update for OS X Server.

Description

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)

Solution

Upgrade to Mac OS X Server version 5.0.3 or later.

Note that OS X Server 5.0.3 is available only for OS X 10.10.5 or later.
