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

The version of OpenSSL installed on the remote AIX host is affected by the following vulnerabilities :

  - A use-after-free condition exists in the     d2i_ECPrivateKey() function due to improper processing     of malformed EC private key files during import. A     remote attacker can exploit this to dereference or free     already freed memory, resulting in a denial of service     or other unspecified impact. (CVE-2015-0209)

  - An invalid read flaw exists in the ASN1_TYPE_cmp()     function due to improperly performed boolean-type     comparisons. A remote attacker can exploit this, via a     crafted X.509 certificate to an endpoint that uses the     certificate-verification feature, to cause an invalid     read operation, resulting in a denial of service.
    (CVE-2015-0286)

  - A flaw exists in the ASN1_item_ex_d2i() function due to     a failure to reinitialize 'CHOICE' and 'ADB' data     structures when reusing a structure in ASN.1 parsing.
    This allows a remote attacker to cause an invalid write     operation and memory corruption, resulting in a denial     of service. (CVE-2015-0287)

  - A NULL pointer dereference flaw exists in the     X509_to_X509_REQ() function due to improper processing     of certificate keys. This allows a remote attacker, via     a crafted X.509 certificate, to cause a denial of     service. (CVE-2015-0288)

  - A NULL pointer dereference flaw exists in the PKCS#7     parsing code due to incorrect handling of missing outer     ContentInfo. This allows a remote attacker, using an     application that processes arbitrary PKCS#7 data and     providing malformed data with ASN.1 encoding, to cause     a denial of service. (CVE-2015-0289)

  - An integer underflow condition exists in the     EVP_DecodeUpdate() function due to improper validation     of base64 encoded input when decoding. This allows a     remote attacker, using maliciously crafted base64 data,     to cause a segmentation fault or memory corruption,     resulting in a denial of service or possibly the     execution of arbitrary code. (CVE-2015-0292)

  - A flaw exists in servers that both support SSLv2 and     enable export cipher suites due to improper     implementation of SSLv2. A remote attacker can exploit     this, via a crafted CLIENT-MASTER-KEY message, to cause     a denial of service. (CVE-2015-0293)

Use-after-free vulnerability in the d2i_ECPrivateKey function in crypto/ec/ec_asn1.c in OpenSSL before 0.9.8zf, 1.0.0 before 1.0.0r, 1.0.1 before 1.0.1m, and 1.0.2 before 1.0.2a might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impacts via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import. (CVE-2015-0209)

Updated openssl packages that fix several security issues and one bug are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.

An invalid pointer use flaw was found in OpenSSL's ASN1_TYPE_cmp() function. A remote attacker could crash a TLS/SSL client or server using OpenSSL via a specially crafted X.509 certificate when the attacker-supplied certificate was verified by the application.
(CVE-2015-0286)

An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input (such as a PEM file) could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded. (CVE-2015-0292)

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled.
(CVE-2015-0293)

A use-after-free flaw was found in the way OpenSSL imported malformed Elliptic Curve private keys. A specially crafted key file could cause an application using OpenSSL to crash when imported. (CVE-2015-0209)

An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash. (CVE-2015-0287)

A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate handling implementation. A specially crafted X.509 certificate could cause an application using OpenSSL to crash if the application attempted to convert the certificate to a certificate request. (CVE-2015-0288)

A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. (CVE-2015-0289)

Red Hat would like to thank the OpenSSL project for reporting CVE-2015-0286, CVE-2015-0287, CVE-2015-0288, CVE-2015-0289, CVE-2015-0292, and CVE-2015-0293. Upstream acknowledges Stephen Henson of the OpenSSL development team as the original reporter of CVE-2015-0286, Emilia Käsper of the OpenSSL development team as the original reporter of CVE-2015-0287, Brian Carpenter as the original reporter of CVE-2015-0288, Michal Zalewski of Google as the original reporter of CVE-2015-0289, Robert Dugal and David Ramos as the original reporters of CVE-2015-0292, and Sean Burford of Google and Emilia Käsper of the OpenSSL development team as the original reporters of CVE-2015-0293.

This update also fixes the following bug :

* When a wrapped Advanced Encryption Standard (AES) key did not require any padding, it was incorrectly padded with 8 bytes, which could lead to data corruption and interoperability problems. With this update, the rounding algorithm in the RFC 5649 key wrapping implementation has been fixed. As a result, the wrapped key conforms to the specification, which prevents the described problems.
(BZ#1197667)

All openssl users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

According to the web server's banner, the version of HP System Management Homepage (SMH) hosted on the remote web server is prior to 7.5.0. It is, therefore, affected by multiple vulnerabilities :

  - A flaw exists within the 'mod_deflate' module when     handling highly compressed bodies. A remote attacker can     exploit this, via a specially crafted request, to     exhaust memory and CPU resources, resulting in a denial     of service condition. (CVE-2014-0118)

  - The 'mod_status' module contains a race condition that     can be triggered when handling the scoreboard. A remote     attacker can exploit this to cause a denial of service,     execute arbitrary code, or obtain sensitive credential     information. (CVE-2014-0226)

  - The 'mod_cgid' module lacks a time out mechanism. A     remote attacker can exploit this, via a specially     crafted request, to cause child processes to linger     indefinitely, filling up the scoreboard and resulting in     a denial of service vulnerability. (CVE-2014-0231)

  - A flaw exists in WinNT MPM versions 2.4.1 to 2.4.9 when     using the default AcceptFilter. An attacker can exploit     this, via specially crafted requests. to create a memory     leak, resulting in a denial of service condition.
    (CVE-2014-3523)

  - A NULL pointer dereference flaw exists when the SSLv3     option isn't enabled and an SSLv3 ClientHello is     received. This allows a remote attacker, using an     unexpected handshake, to crash the daemon, resulting in     a denial of service. (CVE-2014-3569)

  - The BIGNUM squaring (BN_sqr) implementation does not     properly calculate the square of a BIGNUM value. This     allows remote attackers to defeat cryptographic     protection mechanisms. (CVE-2014-3570)

  - A NULL pointer dereference flaw exists in the     dtls1_get_record() function when handling DTLS messages.
    A remote attacker, using a specially crafted DTLS     message, can cause a denial of service. (CVE-2014-3571)

  - A flaw exists with ECDH handshakes when using an ECDSA     certificate without a ServerKeyExchange message. This     allows a remote attacker to trigger a loss of forward     secrecy from the ciphersuite. (CVE-2014-3572)

  - A use-after-free error exists in the     'process_nested_data' function within     'ext/standard/var_unserializer.re' due to improper     handling of duplicate keys within the serialized     properties of an object. A remote attacker, using a     specially crafted call to the 'unserialize' method, can     exploit this flaw to execute arbitrary code on the     system. (CVE-2014-8142)

  - A flaw exists when accepting non-DER variations of     certificate signature algorithms and signature encodings     due to a lack of enforcement of matches between signed     and unsigned portions. A remote attacker, by including     crafted data within a certificate's unsigned portion,     can bypass fingerprint-based certificate-blacklist     protection mechanisms. (CVE-2014-8275)

  - An out-of-bounds read flaw in file 'cgi_main.c' exists     when nmap is used to process an invalid file that begins     with a hash character (#) but lacks a newline character.
    A remote attacker, using a specially crafted PHP file,     can exploit this vulnerability to disclose memory     contents, cause a denial of service, or possibly execute     code. (CVE-2014-9427)

  - An out-of-bounds read error exists in the Fine Free File     component that is bundled with PHP. A remote attacker     can exploit this to cause a denial of service condition     or the disclosure of sensitive information.
    (CVE-2014-9652)

  - A memory corruption issue exists in the Fine Free File     component that is bundled with PHP. A remote attacker     can exploit this to cause an unspecified impact.
    (CVE-2014-9653)

  - A heap buffer overflow condition exists in PHP in the     enchant_broker_request_dict() function due to improper     validation of user-supplied input. An attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2014-9705)

  - A security feature bypass vulnerability, known as FREAK     (Factoring attack on RSA-EXPORT Keys), exists due to the     support of weak EXPORT_RSA cipher suites with keys less     than or equal to 512 bits. A man-in-the-middle attacker     may be able to downgrade the SSL/TLS connection to use     EXPORT_RSA cipher suites which can be factored in a     short amount of time, allowing the attacker to intercept     and decrypt the traffic. (CVE-2015-0204)

  - A flaw exists when accepting DH certificates for client     authentication without the CertificateVerify message.
    This allows a remote attacker to authenticate to the     service without a private key. (CVE-2015-0205)

  - A memory leak occurs in dtls1_buffer_record()     when handling a saturation of DTLS records containing     the same number sequence but for the next epoch. This     allows a remote attacker to cause a denial of service.
    (CVE-2015-0206)

  - A flaw exists in the DTLSv1_listen() function due to     state being preserved in the SSL object from one     invocation to the next. A remote attacker can exploit     this, via crafted DTLS traffic, to cause a segmentation     fault, resulting in a denial of service.
    (CVE-2015-0207)

  - A flaw exists in the rsa_item_verify() function due to     improper implementation of ASN.1 signature verification.
    A remote attacker can exploit this, via an ASN.1     signature using the RSA PSS algorithm and invalid     parameters, to cause a NULL pointer dereference,     resulting in a denial of service. (CVE-2015-0208)

  - A use-after-free condition exists in the     d2i_ECPrivateKey() function due to improper processing     of malformed EC private key files during import. A     remote attacker can exploit this to dereference or free     already freed memory, resulting in a denial of service     or other unspecified impact. (CVE-2015-0209)

  - A use-after-free memory error exists in the     process_nested_data() function in 'var_unserializer.re'     due to improper handling of duplicate numerical keys     within the serialized properties of an object. A remote     attacker, using a crafted unserialize method call, can     exploit this vulnerability to execute arbitrary code.
    (CVE-2015-0231)

  - A flaw exists in the exif_process_unicode() function in     'exif.c' that allows freeing an uninitialized pointer. A     remote attacker, using specially crafted EXIF data in a     JPEG image, can exploit this to cause a denial of     service or to execute arbitrary code. (CVE-2015-0232)

  - A use-after-free flaw exists in the function     php_date_timezone_initialize_from_hash() within the     'ext/date/php_date.c' script. An attacker can exploit     this to access sensitive information or crash     applications linked to PHP. (CVE-2015-0273)

  - A flaw exists in the ssl3_client_hello() function due to     improper validation of a PRNG seed before proceeding     with a handshake, resulting in insufficient entropy and     predictable output. This allows a man-in-the-middle     attacker to defeat cryptographic protection mechanisms     via a brute-force attack, resulting in the disclosure of     sensitive information. (CVE-2015-0285)

  - An invalid read error exists in the ASN1_TYPE_cmp()     function due to improperly performed boolean-type     comparisons. A remote attacker can exploit this, via a     crafted X.509 certificate to an endpoint that uses the     certificate-verification feature, to cause an invalid     read operation, resulting in a denial of service.
    (CVE-2015-0286)

  - A flaw exists in the ASN1_item_ex_d2i() function due to     a failure to reinitialize 'CHOICE' and 'ADB' data     structures when reusing a structure in ASN.1 parsing.

  - A flaw exists with the 'multiblock' feature in the     ssl3_write_bytes() function due to improper handling of     certain non-blocking I/O cases. This allows a remote     attacker to cause failed connections or a segmentation     fault, resulting in a denial of service. (CVE-2015-0290)

  - A NULL pointer dereference flaw exists when handling     clients attempting to renegotiate using an invalid     signature algorithm extension. A remote attacker can     exploit this to cause a denial of service.
    (CVE-2015-0291)

  - An integer underflow condition exists in the     EVP_DecodeUpdate() function due to improper validation     of base64 encoded input when decoding. This allows a     remote attacker, using maliciously crafted base64 data,     to cause a segmentation fault or memory corruption,     resulting in a denial of service or possibly the     execution of arbitrary code. (CVE-2015-0292)

  - A flaw exists in servers that both support SSLv2 and     enable export cipher suites due to improper     implementation of SSLv2. A remote attacker can exploit     this, via a crafted CLIENT-MASTER-KEY message, to cause     a denial of service. (CVE-2015-0293)

  - A flaw exists in the ssl3_get_client_key_exchange()     function when client authentication and an ephemeral     Diffie-Hellman ciphersuite are enabled. This allows a     remote attacker, via a ClientKeyExchange message with a     length of zero, to cause a denial of service.
    (CVE-2015-1787)

  - A cross-site request forgery (XSRF) vulnerability exists     due to the lack of a unique token when performing     sensitive actions via HTTP requests. (CVE-2015-2134)

  - A use-after-free error exists in the function     phar_rename_archive() in file 'phar_object.c'. A remote     attacker, by attempting to rename a phar archive to an     already existing file name, can exploit this to cause     a denial of service. (CVE-2015-2301)

  - A use-after-free error exists related to function     'unserialize', which can allow a remote attacker to     execute arbitrary code. Note that this issue is due to     an incomplete fix for CVE-2014-8142. (CVE-2015-0231)

  - A filter bypass vulnerability exists due to a flaw in     the move_uploaded_file() function in which pathnames are     truncated when a NULL byte is encountered. This allows a     remote attacker, via a crafted second argument, to     bypass intended extension restrictions and create files     with unexpected names. (CVE-2015-2348)

  - A user-after-free error exists in the     process_nested_data() function. This allows a remote     attacker, via a crafted unserialize call, to dereference     already freed memory, resulting in the execution of     arbitrary code. (CVE-2015-2787)

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has openssl packages installed that are affected by multiple vulnerabilities:

  - In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances     where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection     were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other     places in the script where the file names of certificates being hashed were possibly passed to a command     executed through the shell. This script is distributed by some operating systems in a manner where it is     automatically executed. On such operating systems, an attacker could execute arbitrary commands with the     privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the     OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in     OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze). (CVE-2022-2068)

  - The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat     Extension packets, which allows remote attackers to obtain sensitive information from process memory via     crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to     d1_both.c and t1_lib.c, aka the Heartbleed bug. (CVE-2014-0160)

  - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service     (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled     error condition. (CVE-2006-2937)

  - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial     of service (CPU consumption) via parasitic public keys with large (1) public exponent or (2) public     modulus values in X.509 certificates that require extra time to process when using RSA signature     verification. (CVE-2006-2940)

  - Buffer overflow in the SSL_get_shared_ciphers function in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before     0.9.8d, and earlier versions has unspecified impact and remote attack vectors involving a long list of     ciphers. (CVE-2006-3738)

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