CVE-2015-8876 – php: Zend/zend_exceptions.c does not validate certain Exception objects
https://notcve.org/view.php?id=CVE-2015-8876
Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 does not validate certain Exception objects, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or trigger unintended method execution via crafted serialized data. Zend/zend_exceptions.c en PHP en versiones anteriores a 5.4.44, 5.5.x en versiones anteriores a 5.5.28 y 5.6.x en versiones anteriores a 5.6.12 no valida ciertos objetos Exception, lo que permite atacantes remotos provocar una denegación del servicio (referencia a puntero NULO y caída de aplicación) o desencadenar la ejecución de un método no previsto a través de datos serializados manipulados. • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.php.net/ChangeLog-5.php https://bugs.php.net/bug.php?id=70121 https://access.redhat.com/security/cve/CVE-2015-8876 https://bugzilla.redhat.com/show_bug.cgi?id=1338896 • CWE-502: Deserialization of Untrusted Data •
CVE-2015-8877 – gd: gdImageScaleTwoPass function in gd_interpolation.c uses inconsistent allocate and free approaches
https://notcve.org/view.php?id=CVE-2015-8877
The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function. La función gdImageScaleTwoPass en gd_interpolation.c en el GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.0, como es utilizado en PHP en versiones anteriores a 5.6.12, usa asignaciones inconsistentes y enfoques libres, lo que permite a atacantes remotos provocar una denegación del servicio (consumo de memoria) a través de una llamada manipulada, según lo demostrado mediante una llamada a la función PHP imagescale. • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3587 http://www.php.net/ChangeLog-5.php http://www.ubuntu.com/usn/USN-2987-1 https://bugs.php.net/bug.php?id=70064 https://github.com/libgd/libgd/commit/4751b606fa38edc456d627140898a7ec679fcc24 https://github.com/libgd/libgd/issues/173 https://access.redhat.com/security/cve/CVE-2015-8877 https://bugzilla.redhat.com/show_bug.cgi?id=1338907 • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-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 •
