CVSS: 10.0EPSS: 9%CPEs: 41EXPL: 1CVE-2015-4602 – php: Incomplete Class unserialization type confusion
https://notcve.org/view.php?id=CVE-2015-4602
The __PHP_Incomplete_Class function in ext/standard/incomplete_class.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an unexpected data type, related to a "type confusion" issue. La función __PHP_Incomplete_Class en ext/standard/incomplete_class.c en PHP en versiones anteriores a 5.4.40, 5.5.x en versiones anteriores a 5.5.24 y 5.6.x en versiones anteriores a 5.6.8 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de un tipo de dato no esperado, relacionado con un caso "type confusion". A flaw was discovered in the way PHP performed object unserialization. Specially crafted input processed by the unserialize() function could cause a PHP application to crash or, possibly, execute arbitrary code. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=fb83c76deec58f1fab17c350f04c9f042e5977d1 http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1135.html http://rhn.redhat.com/errata/RHSA-2015-1186.html http://rhn.redhat.com/errata/RHSA-2015-1187.html http://rhn.redhat.com/errata/RHSA-2015-1218.html http://www.openwall.com/lists/oss-security/2015/06/16/12 http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityf • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

https://notcve.org/view.php?id=CVE-2015-2325
The compile_branch function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code, cause a denial of service (out-of-bounds heap read and crash), or possibly have other unspecified impact via a regular expression with a group containing a forward reference repeated a large number of times within a repeated outer group that has a zero minimum quantifier. La función compile_branch en PCRE versiones anteriores a 8.37, permite a atacantes dependiendo del contexto compilar código incorrecto, causar una denegación de servicio (lectura de la pila fuera de límites y bloqueo) o posiblemente tener otro impacto no especificado por medio de una expresión regular con un grupo que contiene una referencia directa repetida una gran número de veces dentro de un grupo externo repetido que posee un cuantificador mínimo cero. • http://lists.opensuse.org/opensuse-updates/2015-05/msg00014.html https://bugs.exim.org/show_bug.cgi?id=1591 https://fortiguard.com/zeroday/FG-VD-15-015 https://www.pcre.org/original/changelog.txt https://access.redhat.com/security/cve/CVE-2015-2325 https://bugzilla.redhat.com/show_bug.cgi?id=1207198 • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2015-2326
The pcre_compile2 function in PCRE before 8.37 allows context-dependent attackers to compile incorrect code and cause a denial of service (out-of-bounds read) via regular expression with a group containing both a forward referencing subroutine call and a recursive back reference, as demonstrated by "((?+1)(\1))/". La función pcre_compile2 en PCRE versiones anteriores a 8.37, permite a atacantes dependiendo del contexto compilar código incorrecto y causar una denegación de servicio (lectura fuera de límites) mediante una expresión regular con un grupo que contiene una llamada de subrutina de referencia directa y una referencia inversa recursiva, como es demostrado por "((? +1)(\1))/". • http://lists.opensuse.org/opensuse-updates/2015-05/msg00014.html https://bugs.exim.org/show_bug.cgi?id=1592 https://fortiguard.com/zeroday/FG-VD-15-016 https://www.pcre.org/original/changelog.txt https://access.redhat.com/security/cve/CVE-2015-2326 https://bugzilla.redhat.com/show_bug.cgi?id=1207202 • CWE-125: Out-of-bounds Read •

The phar_parse_metadata function in ext/phar/phar.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 allows remote attackers to cause a denial of service (heap metadata corruption) or possibly have unspecified other impact via a crafted tar archive. La función phar_parse_metadata en ext/phar/phar.c en PHP anterior a 5.4.40, 5.5.x anterior a 5.5.24, y 5.6.x anterior a 5.6.8 permite a atacantes remotos causar una denegación de servicio (corrupción de metadatos de la memoria dinámica) o posiblemente tener otro impacto no especificado a través de un archivo tar manipulado. An invalid free flaw was found in the way PHP's Phar extension parsed Phar archives.

https://notcve.org/view.php?id=CVE-2015-4021
The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive. La función phar_parse_tarfile en ext/phar/tar.c en PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 no verifica que el primer caracter de un nombre de fichero es diferente al caracter \0, lo que permite a atacantes remotos causar una denegación de servicio (desbordamientos de enteros y corrupción de memoria) a través de una entrada manipulada en un archivo tar. An integer underflow flaw leading to out-of-bounds memory access was found in the way PHP's Phar extension parsed Phar archives.
