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 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.

CVSS: 7.5EPSS: 3%CPEs: 61EXPL: 1CVE-2015-4022 – php: integer overflow leading to heap overflow when reading FTP file listing
https://notcve.org/view.php?id=CVE-2015-4022
Integer overflow in the ftp_genlist function in ext/ftp/ftp.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 allows remote FTP servers to execute arbitrary code via a long reply to a LIST command, leading to a heap-based buffer overflow. Desbordamiento de enteros en la función ftp_genlist en ext/ftp/ftp.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 permite a servidores FTP remotos ejecutar código arbitrario a través de una contestación larga a un comando LIST, que conduce a un desbordamiento de buffer basado en memoria dinámica. An integer overflow flaw leading to a heap-based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code. • 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-122: Heap-based Buffer Overflow CWE-189: Numeric Errors •

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-2015-4026
The pcntl_exec implementation in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 truncates a pathname upon encountering a \x00 character, which might allow remote attackers to bypass intended extension restrictions and execute files with unexpected names via a crafted first argument. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243. La implementación pcntl_exec en PHP anterior a 5.4.41, 5.5.x anterior a 5.5.25, y 5.6.x anterior a 5.6.9 trunca un nombre de ruta al encontrar un caracter \x00, lo que podría permitir a atacantes remotos evadir las restricciones de extensión y ejecutar ficheros con nombres no esperados a través de un argumento inicial manipulado. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2006-7243. It was found that certain PHP functions did not properly handle file names containing a NULL character. • 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-19: Data Processing Errors CWE-626: Null Byte Interaction Error (Poison Null Byte) •
