CVSS: 7.5EPSS: 95%CPEs: 81EXPL: 2CVE-2013-6420 – PHP - 'openssl_x509_parse()' Memory Corruption
https://notcve.org/view.php?id=CVE-2013-6420
The asn1_time_to_time_t function in ext/openssl/openssl.c in PHP before 5.3.28, 5.4.x before 5.4.23, and 5.5.x before 5.5.7 does not properly parse (1) notBefore and (2) notAfter timestamps in X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted certificate that is not properly handled by the openssl_x509_parse function. La función asn1_time_to_time_t en ext / openssl / openssl.c en PHP anterior a 5.3.28, 5.4.x aterior a 5.4.23 y 5.5.x anterior de 5.5.7 no trata correctamente las marcas de tiempo (timestamps) (1) notBefore y (2) notAfter en certificados X 0.509 , lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un certificado manipulado que no está tratado adecuadamente por la función openssl_x509_parse. The PHP function openssl_x509_parse() uses a helper function called asn1_time_to_time_t() to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated buffer. This problem can be triggered by x509 certificates that contain NUL bytes in their notBefore and notAfter timestamp fields and leads to a memory corruption that might result in arbitrary code execution. • https://www.exploit-db.com/exploits/30395 http://forums.interworx.com/threads/8000-InterWorx-Version-5-0-14-Released-on-Beta-Channel%21 http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=c1224573c773b6845e83505f717fbf820fc18415 http://lists.opensuse.org/opensuse-updates/2013-12/msg00125.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00126.html http://rhn.redhat.com/errata/RHSA-2013-1813.html http://rhn.redhat.com/errata/RHSA-2013-1815.html http://rhn.redhat.com/errata/RHSA • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 5.0EPSS: 59%CPEs: 15EXPL: 0CVE-2013-6712 – php: heap-based buffer over-read in DateInterval
https://notcve.org/view.php?id=CVE-2013-6712
The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification. La función de análisis en ext/date/lib/parse_iso_intervals.c de PHP hasta la versión 5.5.6 no restringe adecuadamente la creación de objetos DateInterval, lo que podría permitir a atacantes remotos provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) a través de una especificación de intervalo manipulada. A buffer over-read flaw was found in the way the DateInterval class parsed interval specifications. An attacker able to make a PHP application parse a specially crafted specification using DateInterval could possibly cause the PHP interpreter to crash. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=12fe4e90be7bfa2a763197079f68f5568a14e071 http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00125.html http://lists.opensuse.org/opensuse-updates/2013-12/msg00126.html http://rhn.redhat.com/errata/RHSA-2014-1765.html http://www.debian.org/security/2013/dsa-2816 http://www.ubuntu.com/usn/USN-2055-1 https://bugs.php.net/bug.php?id=66060 https://h20564&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

The openssl_x509_parse function in openssl.c in the OpenSSL module in PHP before 5.4.18 and 5.5.x before 5.5.2 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.

The Zend Engine in PHP before 5.4.16 RC1, and 5.5.0 before RC2, does not properly determine whether a parser error occurred, which allows context-dependent attackers to cause a denial of service (memory consumption and application crash) via a crafted function definition, as demonstrated by an attack within a shared web-hosting environment. NOTE: the vendor's http://php.net/security-note.php page says "for critical security situations you should be using OS-level security by running multiple web servers each as their own user id. ** EN DISPUTA ** El Zend Engine en PHP anterior a v5.4.16 RC1, y v5.5.0 anterior a RC2, no determina de forma precisa si ocurre un error del analizador sintáctica, lo que permite a atacantes dependiendo del contexto provocar una denegación de servicio (consumo de memoria y caída de la aplicación) a través de una definición de una función manipulada, como se demostró por un ataque en un entorno de alojamiento Web.
