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.

    NASL id SL_20150324_OPENSSL_ON_SL7_X.NASL
    description 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) 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. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

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.

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.

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. It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method. (CVE-2015-0204) 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.

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) Multiple flaws were found in the way OpenSSL parsed X.509 certificates. An attacker could use these flaws to modify an X.509 certificate to produce a certificate with a different fingerprint without invalidating its signature, and possibly bypass fingerprint-based blacklisting in applications. (CVE-2014-8275) 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.

This could be exploited over SSL connections with client supplied keys. (CVE-2015-0209) - A segmentation fault in ASN1_TYPE_cmp was fixed that could be exploited by attackers when e.g. client authentication is used. This could be exploited over SSL connections. (CVE-2015-0286) - A ASN.1 structure reuse memory corruption was fixed. This problem can not be exploited over regular SSL connections, only if specific client programs use specific ASN.1 routines. (CVE-2015-0287) - A X509_to_X509_REQ NULL pointer dereference was fixed, which could lead to crashes. This function is not commonly used, and not reachable over SSL methods. (CVE-2015-0288) - Several PKCS7 NULL pointer dereferences were fixed, which could lead to crashes of programs using the PKCS7 APIs. The SSL apis do not use those by default. (CVE-2015-0289) - Various issues in base64 decoding were fixed, which could lead to crashes with memory corruption, for instance by using attacker supplied PEM data. (CVE-2015-0292) - Denial of service via reachable assert in SSLv2 servers, could be used by remote attackers to terminate the server process. Note that this requires SSLv2 being allowed, which is not the default. (CVE-2015-0293) - A memory leak in the TLS hostname extension was fixed, which could be used by remote attackers to run SSL services out of memory. (CVE-2009-5146)

    description From Red Hat Security Advisory 2015:0800 : Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5 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. It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method. (CVE-2015-0204) 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) Multiple flaws were found in the way OpenSSL parsed X.509 certificates. An attacker could use these flaws to modify an X.509 certificate to produce a certificate with a different fingerprint without invalidating its signature, and possibly bypass fingerprint-based blacklisting in applications. (CVE-2014-8275) 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.

    NASL id SUSE_SU-2015-0553-1.NASL
    description OpenSSL was updated to fix various security issues. Following security issues were fixed : - CVE-2015-0209: A Use After Free following d2i_ECPrivatekey error was fixed which could lead to crashes for attacker supplied Elliptic Curve keys. This could be exploited over SSL connections with client supplied keys. - CVE-2015-0286: A segmentation fault in ASN1_TYPE_cmp was fixed that could be exploited by attackers when e.g. client authentication is used. This could be exploited over SSL connections. - CVE-2015-0287: A ASN.1 structure reuse memory corruption was fixed. This problem can not be exploited over regular SSL connections, only if specific client programs use specific ASN.1 routines. - CVE-2015-0288: A X509_to_X509_REQ NULL pointer dereference was fixed, which could lead to crashes. This function is not commonly used, and not reachable over SSL methods. - CVE-2015-0289: Several PKCS7 NULL pointer dereferences were fixed, which could lead to crashes of programs using the PKCS7 APIs. The SSL apis do not use those by default. - CVE-2015-0292: Various issues in base64 decoding were fixed, which could lead to crashes with memory corruption, for instance by using attacker supplied PEM data. - CVE-2015-0293: Denial of service via reachable assert in SSLv2 servers, could be used by remote attackers to terminate the server process. Note that this requires SSLv2 being allowed, which is not the default. - CVE-2009-5146: A memory leak in the TLS hostname extension was fixed, which could be used by remote attackers to run SSL services out of memory. 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.

  • NASL family CGI abuses
    NASL id SPLUNK_618.NASL
    description According to its version number, the Splunk Enterprise hosted on the remote web server is 5.0.x prior to 5.0.13, 6.0.x prior to 6.0.9, or 6.1.x prior to 6.1.4. It is, therefore, affected by the following vulnerabilities related to the included OpenSSL library : - 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 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 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 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) - 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) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
