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)

According to its self-reported version number, the Puppet Enterprise application running on the remote host is 3.x prior to 3.8.1. It is, therefore, affected by the following vulnerabilities :

  - An XML external entity injection (XXE) flaw exists in     the Apache ActiveMQ component due to a faulty     configuration that allows an XML parser to accept XML     external entities from untrusted sources. A remote     attacker, by sending crafted XML data, can exploit this     to disclose arbitrary files. (CVE-2014-3600)

  - An authentication bypass vulnerability exists in the     Apache ActiveMQ component due to a flaw in the     LDAPLoginModule implementation. A remote attacker can     exploit this to bypass authentication mechanisms.
    (CVE-2014-3612)

  - Multiple cross-site scripting vulnerabilities exist in     the administrative console of Apache ActiveMQ that allow     a remote attacker to inject arbitrary HTML or web     scripts. (CVE-2014-8110)

  - An invalid free memory error exists due to improper     validation of user-supplied input when a DTLS peer     receives application data between ChangeCipherSpec and     Finished messages. A remote attacker can exploit this to     corrupt memory, resulting in a denial of service or     the execution of arbitrary code. (CVE-2014-8176)

  - A denial of service vulnerability exists when processing     an ECParameters structure due to an infinite loop that     occurs when a specified curve is over a malformed binary     polynomial field. A remote attacker can exploit this to     perform a denial of service against any system that     processes public keys, certificate requests, or     certificates. This includes TLS clients and TLS servers     with client authentication enabled. (CVE-2015-1788)

  - A denial of service vulnerability exists due to improper     validation of the content and length of the ASN1_TIME     string by the X509_cmp_time() function. A remote     attacker can exploit this, via a malformed certificate     and CRLs of various sizes, to cause a segmentation     fault, resulting in a denial of service condition. TLS     clients that verify CRLs are affected. TLS clients and     servers with client authentication enabled may be     affected if they use custom verification callbacks.
    (CVE-2015-1789)

  - A NULL pointer dereference flaw exists in the PKCS#7     parsing code due to incorrect handling of missing inner     'EncryptedContent'. This allows a remote attacker, via     specially crafted ASN.1-encoded PKCS#7 blobs with     missing content, to cause a denial of service condition     or other potential unspecified impacts. (CVE-2015-1790)

  - A double-free error exists due to a race condition that     occurs when a NewSessionTicket is received by a     multi-threaded client when attempting to reuse a     previous ticket. (CVE-2015-1791)

  - A denial of service vulnerability exists in the CMS code     due to an infinite loop that occurs when verifying a     signedData message. A remote attacker can exploit this     to cause a denial of service condition. (CVE-2015-1792)

  - A double-free memory flaw exists in PostgreSQL due to     a timeout interrupt occurring partway in the session     shutdown sequence. A remote attacker, by closing     an SSL session when the authentication timeout expires,     can exploit this flaw to cause a denial of service.
    (CVE-2015-3165)

  - An out-of-memory condition exists in the printf()     functions in PostgreSQL due to a failure to check for     errors. A remote attacker can exploit this to access     sensitive information. (CVE-2015-3166)

  - A flaw exists in contrib/pgcrypto in PostgreSQL due     to cases of decryption reporting other error message     texts, which a remote attacker can use to recover     keys from other systems. (CVE-2015-3167)

  - A man-in-the-middle vulnerability, known as Logjam,     exists due to a flaw in the SSL/TLS protocol. A remote     attacker can exploit this flaw to downgrade connections     using ephemeral Diffie-Hellman key exchange to 512-bit     export-grade cryptography. (CVE-2015-4000)

PostgreSQL was updated to the security and bugfix release 9.3.8 including 9.3.7.

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 9.0.20, 9.1.x prior to 9.1.16, 9.2.x prior to 9.2.11, 9.3.x prior to 9.3.7, or 9.4.x prior to 9.4.2 and is affected by multiple vulnerabilities :

 - A double free memory error exists after authentication timeout, which a remote attacker can utilize to cause the program to crash. (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)
 - pgcrypto 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 double-free flaw was found in the connection handling. An unauthenticated attacker could exploit this flaw to crash the PostgreSQL back end by disconnecting at approximately the same time as the authentication time out is triggered. (CVE-2015-3165)

It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system is in a state that would cause the standard library functions to fail, for example memory exhaustion, an authenticated user could exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file. (CVE-2015-3166)

It was discovered that the pgcrypto module could return different error messages when decrypting certain data with an incorrect key.
This can help an authenticated user to launch a possible cryptographic attack, although no suitable attack is currently known.

This update also includes changes in PostgreSQL's packaging to prepare for the migration to the new major version 9.4. (FATE#316970, bsc#907651)

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

Several vulnerabilities were discovered in PostgreSQL, a relational database server system. The 8.4 branch is EOLed upstream, but still present in Debian squeeze. This new LTS minor version contains the fixes that were applied upstream to the 9.0.20 version, backported to 8.4.22 which was the last version officially released by the PostgreSQL developers. This LTS effort for squeeze-lts is a community project sponsored by credativ GmbH.

CVE-2015-3165: Remote crash SSL clients disconnecting just before the authentication timeout expires can cause the server to crash.

CVE-2015-3166: Information exposure The replacement implementation of snprintf() failed to check for errors reported by the underlying system library calls; the main case that might be missed is out-of-memory situations. In the worst case this might lead to information exposure.

CVE-2015-3167: Possible side-channel key exposure In contrib/pgcrypto, some cases of decryption with an incorrect key could report other error message texts. Fix by using a one-size-fits-all message.

Note that the next round of minor releases for PostgreSQL have already been scheduled for early June 2015. There will be a corresponding 8.4.22lts3 update at the same time.
