CVSS: 9.8EPSS: 3%CPEs: 30EXPL: 1CVE-2016-4538 – php: bcpowmod accepts negative scale causing heap buffer overflow corrupting _one_ definition
https://notcve.org/view.php?id=CVE-2016-4538
The bcpowmod function in ext/bcmath/bcmath.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 modifies certain data structures without considering whether they are copies of the _zero_, _one_, or _two_ global variable, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted call. La función bcpowmod en ext/bcmath/bcmath.c en PHP en versiones anteriores a 5.5.35, 5.6.x en versiones anteriores a 5.6.21 y 7.x en versiones anteriores a 7.0.6 modifica ciertas estructuras de datos sin considerar si son copias de la variable global _zero_, _one_, o _two_, lo que permite a atacantes remotos provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de una llamada manipulada. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183736.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00027.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3602 http://www.openwall.com/lists/oss-security/2016/05/05/21 http://www.securityfocus.com/bid/90173 https:/ • CWE-20: Improper Input Validation CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2015-8879
The odbc_bindcols function in ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles driver behavior for SQL_WVARCHAR columns, which allows remote attackers to cause a denial of service (application crash) in opportunistic circumstances by leveraging use of the odbc_fetch_array function to access a certain type of Microsoft SQL Server table. La función odbc_bindcols en ext/odbc/php_odbc.c en PHP en versiones anteriores a 5.6.12 no maneja correctamente el comportamiento del controlador para columnas SQL_WVARCHAR, lo que permite a atacantes remotos provocar una denegación del servicio (caída de aplicación) en circunstancias oportunas aprovechando el uso de la función odbc_fetch_array para acceder a determinado tipo de tablas Microsoft SQL Server. • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.php.net/ChangeLog-5.php https://bugs.php.net/bug.php?id=69975 https://access.redhat.com/security/cve/CVE-2015-8879 https://bugzilla.redhat.com/show_bug.cgi?id=1338912 • CWE-20: Improper Input Validation •

The xml_parse_into_struct function in ext/xml/xml.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 allows remote attackers to cause a denial of service (buffer under-read and segmentation fault) or possibly have unspecified other impact via crafted XML data in the second argument, leading to a parser level of zero. La función xml_parse_into_struct en ext/xml/xml.c en PHP en versiones anteriores a 5.5.35, 5.6.x en versiones anteriores a 5.6.21 y 7.x en versiones anteriores a 7.0.6 permite a atacantes remotos provocar una denegación de servicio (lectura debajo de buffer y fallo de segmentación) o posiblemente tener otro impacto no especificado a través de un dato XML manipulado en el argumento segundo, encabezando un analizador de nivel cero. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183736.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-06/msg00027.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3602 http://www.openwall.com/lists/oss-security/2016/05/05/21 http://www.securityfocus.com/bid/90174 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
