CVSS: 5.0EPSS: 1%CPEs: 33EXPL: 0CVE-2015-0289 – openssl: PKCS7 NULL pointer dereference
https://notcve.org/view.php?id=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 does not properly handle a lack of outer ContentInfo, which allows 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. La implementación PKCS#7 en OpenSSL anterior a 0.9.8zf, 1.0.0 anterior a 1.0.0r, 1.0.1 anterior a 1.0.1m, y 1.0.2 anterior a 1.0.2a no maneja correctamente la falta de ContentInfo exterior, lo que permite a atacantes causar una denegación de servicio (referencia a puntero nulo y caída de aplicación) mediante el aprovechamiento de una aplicación que procesa datos PKCS#7 arbitrarios y la provisión de datos malformados con una codificación ASN.1, relacionado con crypto/pkcs7/pk7_doit.c y crypto/pkcs7/pk7_lib.c. 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. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.apple.com/archives/security-announce/2015/Jun/msg00002.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/156823.html http://lists.fedoraproject.org/pipermail/package-announce/ • CWE-476: NULL Pointer Dereference •

Integer underflow in the EVP_DecodeUpdate function in crypto/evp/encode.c in the base64-decoding implementation in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via crafted base64 data that triggers a buffer overflow. Subdesbordamiento de enteros en la función EVP_DecodeUpdate en crypto/evp/encode.c en la implementación base64-decoding en OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m, y 1.0.1 anterior a 1.0.1h permite a atacantes remotos causar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto no especificado a través de datos base64 manipulados que provocan un desbordamiento de buffer. 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. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10680 http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152733.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152734.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/152844.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://marc.info/?l=bugtraq&m=143213830203296&w=2 http://marc.info/?l=bugtraq&m=143748090628601&w=2 http://marc.inf • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows 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. OpenSSL anterior a 0.9.8zd, 1.0.0 anterior a 1.0.0p, y 1.0.1 anterior a 1.0.1k no fuerza ciertas limitaciones sobre datos de certificados, lo que permite a atacantes remotos derrotar un mecanismo de protección de lista negra de certificados basado en huellas dactilares mediante la inclusión de datos manipulados dentro de la porción no firmada de un certificado, relacionado con crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, y crypto/x509/x_all.c. 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. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10679 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-January/148363.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00021.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00 • CWE-310: Cryptographic Issues •
