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

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)

The remote host is affected by the vulnerability described in GLSA-201507-20 (PostgreSQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PostgreSQL. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with the       privileges of the process, cause a Denial of Service condition or       escalate privileges.
  Workaround :

    There is no known workaround at this time.

The version of PostgreSQL installed on the remote host is 9.0.x prior to 9.0.19, 9.1.x prior to 9.1.15, 9.2.x prior to 9.2.10, 9.3.x prior to 9.3.6, or 9.4.x prior to 9.4.1 and is affected by multiple vulnerabilities :

 - 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. (CVE-2014-0067)

 - An information disclosure vulnerability exists due to improper handling of restricted column values in constraint-violation error messages. (CVE-2014-8161)

 - Multiple vulnerabilities exist due to several buffer overflow errors related to the 'to_char' functions. (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. (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. (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.(CVE-2015-0244)

The PostgreSQL database server was updated to 9.1.15, fixing bugs and security issues :

  - Fix buffer overruns in to_char(). (CVE-2015-0241)

  - Fix buffer overrun in replacement *printf() functions.
    (CVE-2015-0242)

  - Fix buffer overruns in contrib/pgcrypto. (CVE-2015-0243)

  - Fix possible loss of frontend/backend protocol     synchronization after an error. (CVE-2015-0244)

  - Fix information leak via constraint-violation error     messages (CVE-2014-8161). For a comprehensive list of     fixes, please refer to the following release notes :

  -     http://www.postgresql.org/docs/9.1/static/release-9-1-15     .html

  -     http://www.postgresql.org/docs/9.1/static/release-9-1-14     .html

  -     http://www.postgresql.org/docs/9.1/static/release-9-1-13     .html

Updated postgresql packages fix multiple security vulnerabilities :

Granting a role without ADMIN OPTION is supposed to prevent the grantee from adding or removing members from the granted role, but this restriction was easily bypassed by doing SET ROLE first. The security impact is mostly that a role member can revoke the access of others, contrary to the wishes of his grantor. Unapproved role member additions are a lesser concern, since an uncooperative role member could provide most of his rights to others anyway by creating views or SECURITY DEFINER functions (CVE-2014-0060).

The primary role of PL validator functions is to be called implicitly during CREATE FUNCTION, but they are also normal SQL functions that a user can call explicitly. Calling a validator on a function actually written in some other language was not checked for and could be exploited for privilege-escalation purposes. The fix involves adding a call to a privilege-checking function in each validator function.
Non-core procedural languages will also need to make this change to their own validator functions, if any (CVE-2014-0061).

If the name lookups come to different conclusions due to concurrent activity, we might perform some parts of the DDL on a different table than other parts. At least in the case of CREATE INDEX, this can be used to cause the permissions checks to be performed against a different table than the index creation, allowing for a privilege escalation attack (CVE-2014-0062).

The MAXDATELEN constant was too small for the longest possible value of type interval, allowing a buffer overrun in interval_out().
Although the datetime input functions were more careful about avoiding buffer overrun, the limit was short enough to cause them to reject some valid inputs, such as input containing a very long timezone name.
The ecpg library contained these vulnerabilities along with some of its own (CVE-2014-0063).

Several functions, mostly type input functions, calculated an allocation size without checking for overflow. If overflow did occur, a too-small buffer would be allocated and then written past (CVE-2014-0064).

Use strlcpy() and related functions to provide a clear guarantee that fixed-size buffers are not overrun. Unlike the preceding items, it is unclear whether these cases really represent live issues, since in most cases there appear to be previous constraints on the size of the input string. Nonetheless it seems prudent to silence all Coverity warnings of this type (CVE-2014-0065).

There are relatively few scenarios in which crypt() could return NULL, but contrib/chkpass would crash if it did. One practical case in which this could be an issue is if libc is configured to refuse to execute unapproved hashing algorithms (e.g., FIPS mode) (CVE-2014-0066).

Since the temporary server started by make check uses trust authentication, another user on the same machine could connect to it as database superuser, and then potentially exploit the privileges of the operating-system user who started the tests. A future release will probably incorporate changes in the testing procedure to prevent this risk, but some public discussion is needed first. So for the moment, just warn people against using make check when there are untrusted users on the same machine (CVE-2014-0067).

A user with limited clearance on a table might have access to information in columns without SELECT rights on through server error messages (CVE-2014-8161).

The function to_char() might read/write past the end of a buffer. This might crash the server when a formatting template is processed (CVE-2015-0241).

The pgcrypto module is vulnerable to stack buffer overrun that might crash the server (CVE-2015-0243).

Emil Lenngren reported that an attacker can inject SQL commands when the synchronization between client and server is lost (CVE-2015-0244).

This update provides PostgreSQL versions 9.3.6 and 9.2.10 that fix these issues, as well as several others.

A buffer overflow flaw was found in the way PostgreSQL handled certain numeric formatting. An authenticated database user could use a specially crafted timestamp formatting template to cause PostgreSQL to crash or, under certain conditions, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0241)

A buffer overflow flaw was found in the PostgreSQL's internal printf() implementation. An authenticated database user could use a specially crafted string in a SQL query to cause PostgreSQL to crash or, potentially, lead to privilege escalation. (CVE-2015-0242)

A stack-buffer overflow flaw was found in PostgreSQL's pgcrypto module. An authenticated database user could use this flaw to cause PostgreSQL to crash or, potentially, execute arbitrary code with the permissions of the user running PostgreSQL. (CVE-2015-0243)

A flaw was found in way PostgreSQL handled certain errors during that were generated during protocol synchronization. An authenticated database user could use this flaw to inject queries into an existing connection. (CVE-2015-0244)

The 'make check' command for the test suites in PostgreSQL 9.3.3 and earlier does not properly invoke initdb to specify the authentication requirements for a database cluster to be used for the tests, which allows local users to gain privileges by leveraging access to this cluster. (CVE-2014-0067)

An information leak flaw was found in the way certain the PostgreSQL database server handled certain error messages. An authenticated database user could possibly obtain the results of a query they did not have privileges to execute by observing the constraint violation error messages produced when the query was executed. (CVE-2014-8161)

The version of PostgreSQL installed on the remote host is 9.0.x prior to 9.0.19, 9.1.x prior to 9.1.15, 9.2.x prior to 9.2.10, 9.3.x prior to 9.3.6, or 9.4.x prior to 9.4.1. It is, therefore, affected by multiple vulnerabilities :

  - 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. Note that this issue only affects     Microsoft Windows hosts. (CVE-2014-0067)

  - 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)

  - 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)

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.
