CVSS: 6.8EPSS: 35%CPEs: 17EXPL: 1CVE-2007-2872 – PHP 5.1.6 - 'Chunk_Split()' Integer Overflow
https://notcve.org/view.php?id=CVE-2007-2872
Multiple integer overflows in the chunk_split function in PHP 5 before 5.2.3 and PHP 4 before 4.4.8 allow remote attackers to cause a denial of service (crash) or execute arbitrary code via the (1) chunks, (2) srclen, and (3) chunklen arguments. Los múltiples desbordamientos de enteros en la función chunk_split en PHP versión 5 anterior a 5.2.3 y PHP versión 4 anterior a 4.4.8, permiten a los atacantes remotos causar una denegación de servicio (bloqueo) o ejecutar código arbitrario por medio de los argumentos (1) chunks, (2) srclen, y (3) chunklen. • https://www.exploit-db.com/exploits/30117 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01178795 http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01345501 http://lists.opensuse.org/opensuse-security-announce/2007-07/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2008-01/msg00006.html http://osvdb.org/36083 http://rhn.redhat.com/errata/RHSA-2007-0889.html http://secunia.com/advisories/25456 http://secunia.com/advisories/25535 • CWE-189: Numeric Errors CWE-190: Integer Overflow or Wraparound •

PHP 4.x and 5.x before 5.2.1, when running on multi-threaded systems, does not ensure thread safety for libc crypt function calls using protection schemes such as a mutex, which creates race conditions that allow remote attackers to overwrite internal program memory and gain system access. PHP 4.x y 5.x anterior al 5.2.1, cuando corre bajo sistemas multi-hilo, no asegura la seguridad de los hilos para las llamadas a la función libc crypt utilizando esquemas de protección como el mutex, lo que provoca una condición de carrera que permite a atacantes remotos sobrescribir la memoria de programa interna y obtener acceso al sistema. • http://blog.php-security.org/archives/82-Suhosin-0.9.20-and-crypt-Thread-Safety-Vulnerability.html http://osvdb.org/36088 http://secunia.com/advisories/25434 http://www.securityfocus.com/bid/24109 https://exchange.xforce.ibmcloud.com/vulnerabilities/34601 •

The substr_count function in PHP 5.2.1 and earlier allows context-dependent attackers to obtain sensitive information via unspecified vectors, a different affected function than CVE-2007-1375. La función substr_count en PHP 5.2.1 y versiones anteriores permite a atacantes locales o remotos dependientes del contexto obtener información confidencial mediante vectores no especificados, una función afectada distinta de CVE-2007-1375. • http://osvdb.org/34730 http://secunia.com/advisories/26895 http://us2.php.net/releases/5_2_2.php http://www.attrition.org/pipermail/vim/2007-May/001621.html http://www.mandriva.com/security/advisories?name=MDKSA-2007:187 http://www.novell.com/linux/security/advisories/2007_15_sr.html http://www.securityfocus.com/bid/24012 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys. La función mcrypt_create_iv en ext/mcrypt/mcrypt.c en PHP anterior a 4.4.7, 5.2.1, y posiblemente 5.0.x y otras versiones PHP 5, llaman a php_rand_r con una variable de cabeza de serie no inicializada y por lo tanto siempre genera el mismo vector de inicialización (IV), lo cual podría permitir a atacantes dependientes del contexto desencriptar ciertos datos más fácilmente debido a que las claves de cifrado son más fáciles de adivinar. • http://blog.php-security.org/archives/80-Watching-the-PHP-CVS.html http://bugs.php.net/bug.php?id=40999 http://cvs.php.net/viewvc.cgi/php-src/ext/mcrypt/mcrypt.c?r1=1.91.2.3.2.9&r2=1.91.2.3.2.10 http://osvdb.org/36087 http://secunia.com/advisories/26895 http://www.fortheloot.com/public/mcrypt.patch http://www.mandriva.com/security/advisories?name=MDKSA-2007:187 http://www.novell.com/linux/security/advisories/2007_15_sr.html http://www.php.net& •
