CVE-2015-8878

https://notcve.org/view.php?id=CVE-2015-8878

main/php_open_temporary_file.c in PHP before 5.5.28 and 5.6.x before 5.6.12 does not ensure thread safety, which allows remote attackers to cause a denial of service (race condition and heap memory corruption) by leveraging an application that performs many temporary-file accesses. main/php_open_temporary_file.c en versiones anteriores a 5.5.28 y 5.6.x en versiones anteriores a 5.6.12 no asegura la protección contra amenazas, lo que permite a atacantes remotos provocar una denegación del servicio (condición de carrera y corrupción de la memoria dinámica) aprovechando una aplicación que ejecuta muchos accesos a archivos temporales. • http://www.php.net/ChangeLog-5.php https://bugs.php.net/bug.php?id=70002 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2016-4543 – php: Out-of-bounds heap memory read in exif_read_data() caused by malformed input

https://notcve.org/view.php?id=CVE-2016-4543

The exif_process_IFD_in_JPEG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not validate IFD sizes, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data. La función exif_process_IFD_in_JPEG en ext/exif/exif.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 no valida tamaños IFD, lo que permite a atacantes remotos provocar una denegación de servicio (lectura fuera de límites) o posiblemente tener otro impacto no especificado a través de datos de cabecera manipulados. • 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/89844 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

The exif_process_IFD_TAG function in ext/exif/exif.c in PHP before 5.5.35, 5.6.x before 5.6.21, and 7.x before 7.0.6 does not properly construct spprintf arguments, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via crafted header data.

CVE-2015-8867 – php: openssl_random_pseudo_bytes() is not cryptographically secure

https://notcve.org/view.php?id=CVE-2015-8867

The openssl_random_pseudo_bytes function in ext/openssl/openssl.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 incorrectly relies on the deprecated RAND_pseudo_bytes function, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors. La función openssl_random_pseudo_bytes en ext/openssl/openssl.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 se basa incorrectamente en la función en desuso RAND_pseudo_bytes, lo que hace que sea más fácil para los atacantes remotos vencer a los mecanismos de protección de cifrado a través de vectores no especificados. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=16023f3e3b9c06cf677c3c980e8d574e4c162827 http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00056.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.openwall.com/lists/oss-security/2016/04/24/1 http://www.php.net/ChangeLog-5.php http://www.php.net/ChangeLog-7 • CWE-310: Cryptographic Issues •

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 •
