CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description 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)

    description libressl was updated to version 2.2.1 to fix 16 security issues. LibreSSL is a fork of OpenSSL. Because of that CVEs affecting OpenSSL often also affect LibreSSL. These security issues were fixed : - CVE-2014-3570: The BN_sqr implementation in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k did not properly calculate the square of a BIGNUM value, which might make it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors, related to crypto/bn/asm/mips.pl, crypto/bn/asm/x86_64-gcc.c, and crypto/bn/bn_asm.c (bsc#912296). - CVE-2014-3572: The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allowed remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message (bsc#912015). - CVE-2015-1792: The do_free_upto function in crypto/cms/cms_smime.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allowed remote attackers to cause a denial of service (infinite loop) via vectors that trigger a NULL value of a BIO data structure, as demonstrated by an unrecognized X.660 OID for a hash function (bsc#934493). - CVE-2014-8275: OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k did not enforce certain constraints on certificate data, which allowed remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c (bsc#912018). - CVE-2015-0209: 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 allowed remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed Elliptic Curve (EC) private-key file that is improperly handled during import (bsc#919648). - CVE-2015-1789: The X509_cmp_time function in crypto/x509/x509_vfy.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allowed remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted length field in ASN1_TIME data, as demonstrated by an attack against a server that supports client authentication with a custom verification callback (bsc#934489). - CVE-2015-1788: The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b did not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allowed remote attackers to cause a denial of service (infinite loop) via a session that used an Elliptic Curve algorithm, as demonstrated by an attack against a server that supports client authentication (bsc#934487). - CVE-2015-1790: The PKCS7_dataDecodefunction in crypto/pkcs7/pk7_doit.c in OpenSSL before 0.9.8zg, 1.0.0 before 1.0.0s, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b allowed remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a PKCS#7 blob that used ASN.1 encoding and lacks inner EncryptedContent data (bsc#934491). - CVE-2015-0287: The ASN1_item_ex_d2i function in crypto/asn1/tasn_dec.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 did not reinitialize CHOICE and ADB data structures, which might allowed attackers to cause a denial of service (invalid write operation and memory corruption) by leveraging an application that relies on ASN.1 structure reuse (bsc#922499). - CVE-2015-0286: The ASN1_TYPE_cmp function in crypto/asn1/a_type.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 did not properly perform boolean-type comparisons, which allowed remote attackers to cause a denial of service (invalid read operation and application crash) via a crafted X.509 certificate to an endpoint that used the certificate-verification feature (bsc#922496). - CVE-2015-0289: The PKCS#7 implementation 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 did not properly handle a lack of outer ContentInfo, which allowed attackers to cause a denial of service (NULL pointer dereference and application crash) by leveraging an application that processes arbitrary PKCS#7 data and providing malformed data with ASN.1 encoding, related to crypto/pkcs7/pk7_doit.c and crypto/pkcs7/pk7_lib.c (bsc#922500). - CVE-2015-0288: The X509_to_X509_REQ function in crypto/x509/x509_req.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 allowed attackers to cause a denial of service (NULL pointer dereference and application crash) via an invalid certificate key (bsc#920236). - CVE-2014-8176: The dtls1_clear_queues function in ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h frees data structures without considering that application data can arrive between a ChangeCipherSpec message and a Finished message, which allowed remote DTLS peers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unexpected application data (bsc#934494). - CVE-2015-4000: The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, did not properly convey a DHE_EXPORT choice, which allowed man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the 'Logjam' issue (bsc#931600). - CVE-2015-0205: The ssl3_get_cert_verify function in s3_srvr.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k accepts client authentication with a Diffie-Hellman (DH) certificate without requiring a CertificateVerify message, which allowed remote attackers to obtain access without knowledge of a private key via crafted TLS Handshake Protocol traffic to a server that recognizes a Certification Authority with DH support (bsc#912293). - CVE-2015-0206: Memory leak in the dtls1_buffer_record function in d1_pkt.c in OpenSSL 1.0.0 before 1.0.0p and 1.0.1 before 1.0.1k allowed remote attackers to cause a denial of service (memory consumption) by sending many duplicate records for the next epoch, leading to failure of replay detection (bsc#912292).

It is, therefore, affected by multiple vulnerabilities : - 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.

A remote attacker can exploit this to cause a denial of service condition or other potential unspecified impact. (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) - The symmetric-key feature in the receive function requires a correct message authentication code (MAC) only if the MAC field has a nonzero length. This makes it easier for a man-in-the-middle attacker to spoof packets by omitting the MAC. (CVE-2015-1798) - A flaw exists in the symmetric-key feature in the receive function when handling a specially crafted packet sent to one of two hosts that are peering with each other. This allows an attacker to cause the next attempt by the servers to synchronize to fail. (CVE-2015-1799) - 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) - A flaw exists in the TLS 1.x implementation in the Cavium SDK due to a failure to check the first byte of the padding bytes. A man-in-the-middle attacker can exploit this, by sending specially crafted requests to the server, to induce requests that allow determining the plaintext chunks of data.

    description Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 and 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 free flaw was found in the way OpenSSL handled certain DTLS handshake messages. A malicious DTLS client or server could cause a DTLS server or client using OpenSSL to crash or, potentially, execute arbitrary code. (CVE-2014-8176) A flaw was found in the way the OpenSSL packages shipped with Red Hat Enterprise Linux 6 and 7 performed locking in the ssleay_rand_bytes() function. This issue could possibly cause a multi-threaded application using OpenSSL to perform an out-of-bounds read and crash. (CVE-2015-3216) An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL. A specially crafted X.509 certificate or a Certificate Revocation List (CRL) could possibly cause a TLS/SSL server or client using OpenSSL to crash. (CVE-2015-1789) A race condition was found in the session handling code of OpenSSL. This issue could possibly cause a multi-threaded TLS/SSL client using OpenSSL to double free session ticket data and crash. (CVE-2015-1791) A flaw was found in the way OpenSSL handled Cryptographic Message Syntax (CMS) messages. A CMS message with an unknown hash function identifier could cause an application using OpenSSL to enter an infinite loop. (CVE-2015-1792) A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. A specially crafted PKCS#7 input with missing EncryptedContent data could cause an application using OpenSSL to crash. (CVE-2015-1790) Red Hat would like to thank the OpenSSL project for reporting CVE-2014-8176, CVE-2015-1789, CVE-2015-1790, CVE-2015-1791 and CVE-2015-1792 flaws.

    description LOGJAM: A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange (for both export and non-export grade cipher suites). An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. (CVE-2015-4000) An out-of-bounds read flaw was found in the X509_cmp_time() function of OpenSSL, which is used to test the expiry dates of SSL/TLS certificates. An attacker could possibly use a specially crafted SSL/TLS certificate or CRL (Certificate Revocation List), which when parsed by an application would cause that application to crash. (CVE-2015-1789) 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-2015-1790) A race condition was found in the session handling code of OpenSSL. An attacker could cause a multi-threaded SSL/TLS server to crash. (CVE-2015-1791) A denial of service flaw was found in OpenSSL in the way it verified certain signed messages using CMS (Cryptographic Message Syntax). A remote attacker could cause an application using OpenSSL to use excessive amounts of memory by sending a specially crafted message for verification. (CVE-2015-1792) An invalid-free flaw was found in the way OpenSSL handled certain DTLS handshake messages. A malicious DTLS client or server could send a specially crafted message to the peer, which could cause the application to crash or potentially cause arbitrary code execution. (CVE-2014-8176) A regression was found in the ssleay_rand_bytes() function. This could lead a multi-threaded application to crash. (CVE-2015-3216)

    description Multiple vulnerabilities were discovered in OpenSSL, a Secure Sockets Layer toolkit. - CVE-2014-8176 Praveen Kariyanahalli, Ivan Fratric and Felix Groebert discovered that an invalid memory free could be triggered when buffering DTLS data. This could allow remote attackers to cause a denial of service (crash) or potentially execute arbitrary code. This issue only affected the oldstable distribution (wheezy). - CVE-2015-1788 Joseph Barr-Pixton discovered that an infinite loop could be triggered due to incorrect handling of malformed ECParameters structures. This could allow remote attackers to cause a denial of service. - CVE-2015-1789 Robert Swiecki and Hanno Bock discovered that the X509_cmp_time function could read a few bytes out of bounds. This could allow remote attackers to cause a denial of service (crash) via crafted certificates and CRLs. - CVE-2015-1790 Michal Zalewski discovered that the PKCS#7 parsing code did not properly handle missing content which could lead to a NULL pointer dereference. This could allow remote attackers to cause a denial of service (crash) via crafted ASN.1-encoded PKCS#7 blobs. - CVE-2015-1791 Emilia Kasper discovered that a race condition could occur due to incorrect handling of NewSessionTicket in a multi-threaded client, leading to a double free. This could allow remote attackers to cause a denial of service (crash). - CVE-2015-1792 Johannes Bauer discovered that the CMS code could enter an infinite loop when verifying a signedData message, if presented with an unknown hash function OID. This could allow remote attackers to cause a denial of service. Additionally OpenSSL will now reject handshakes using DH parameters shorter than 768 bits as a countermeasure against the Logjam attack (CVE-2015-4000 ).

  • NASL family AIX Local Security Checks
    NASL id AIX_OPENSSL_ADVISORY14.NASL
    description The version of OpenSSL installed on the remote AIX host is affected by multiple vulnerabilities : - 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 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)
