CVSS: 7.5EPSS: 0%CPEs: 45EXPL: 0CVE-2015-4598 – php: missing null byte checks for paths in DOM and GD extensions
https://notcve.org/view.php?id=CVE-2015-4598
PHP before 5.4.42, 5.5.x before 5.5.26, and 5.6.x before 5.6.10 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function, as demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may write to only .html files. PHP en versiones anteriores a 5.4.42, 5.5.x en versiones anteriores a 5.5.26 y 5.6.x en versiones anteriores a 5.6.10 no asegura que los nombres de ruta carezcan de la secuencia %00, lo que podría permitir a atacantes remotos leer o escribir archivos arbitrarios a través de entrada manipulada para una aplicación que llama a (1) un método para guardar DOMDocument o (2) la función imagepsloadfont GD, según lo demostrado mediante un ataque filename\0.html que elude una configuración prevista en la que los usuarios cliente pueden escribir solamente en archivos .html. It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. • 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://rhn.redhat.com/errata/RHSA-2015-1219.html http://www.debian.org/security/2015/dsa-3344 http://www.openwall.com/lists/oss-security/2015/06/16/12 http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http • CWE-20: Improper Input Validation CWE-626: Null Byte Interaction Error (Poison Null Byte) •

PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8 does not ensure that pathnames lack %00 sequences, which might allow remote attackers to read arbitrary files via crafted input to an application that calls the stream_resolve_include_path function in ext/standard/streamsfuncs.c, as demonstrated by a filename\0.extension attack that bypasses an intended configuration in which client users may read files with only one specific extension. PHP en versiones anteriores a 5.5.40, 5.5.x en versiones anteriores a 5.5.24 y 5.6.x en versiones anteriores a 5.6.8 no asegura que los nombres de ruta carezcan de secuencia %00, lo que permite a atacantes remotos leer archivos arbitrarios a través de una entrada manipulada que llama a la función stream_resolve_include_path en ext/standard/streamsfuncs.c, como se demuestra con un ataque filename\0.extension que eluce una configuración deseada en la que los usuarios cliente pueden leer archivos con sólo una extensión específica.

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 •

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))/".

CVSS: 5.1EPSS: 74%CPEs: 61EXPL: 1CVE-2015-4021 – php: memory corruption in phar_parse_tarfile caused by empty entry file name
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. A specially crafted archive could cause PHP to crash or, possibly, execute arbitrary code when opened. • http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158616.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158915.html http://lists.fedoraproject.org/pipermail/package-announce/2015-May/159031.html http://lists.opensuse.org/opensuse-updates/2015-06/msg00002.html http://php.net/ChangeLog-5.php http://rhn.redhat.com/errata/RHSA-2015-1135.html http://rhn.redhat.com/errata/RHSA-2015&# • CWE-189: Numeric Errors CWE-787: Out-of-bounds Write •
