CVE-2015-4024 – php: multipart/form-data request parsing CPU usage DoS
https://notcve.org/view.php?id=CVE-2015-4024
Algorithmic complexity vulnerability in the multipart_buffer_headers function in main/rfc1867.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 allows remote attackers to cause a denial of service (CPU consumption) via crafted form data that triggers an improper order-of-growth outcome. Vulnerabilidad de complejidad algorítmica en la función multipart_buffer_headers en main/rfc1867.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 permiten a atacantes remotos causar una denegación de servicio (consumo de CPU) a través de datos de formularios manipulados que provocan un resultado de orden de crecimiento incorrecto. A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. • 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-399: Resource Management Errors CWE-407: Inefficient Algorithmic Complexity •
CVE-2015-4025 – php: regressions in 5.4+
https://notcve.org/view.php?id=CVE-2015-4025
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 in certain situations, which allows remote attackers to bypass intended extension restrictions and access files or directories with unexpected names via a crafted argument to (1) set_include_path, (2) tempnam, (3) rmdir, or (4) readlink. NOTE: this vulnerability exists because of an incomplete fix for CVE-2006-7243. 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 en ciertas situaciones, lo que permite a atacantes remotos evadir la restricciones de extensión y acceder a ficheros o directorios con nombres no esperados a través de un argumento manipulado en (1) set_include_path, (2) tempnam, (3) rmdir, o (4) readlink. 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://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 • CWE-19: Data Processing Errors CWE-626: Null Byte Interaction Error (Poison Null Byte) •
CVE-2015-4026 – php: pcntl_exec() accepts paths with NUL character
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.

CVE-2015-3307 – php: invalid pointer free() in phar_tar_process_metadata()
https://notcve.org/view.php?id=CVE-2015-3307
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. 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://rhn.redhat.com/errata/RHSA-2015-1066.html 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://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityfocus.com/bid/74703 https://bugs.php.net/bug.php?id= • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2015-3152 – mysql: use of SSL/TLS can not be enforced in mysql client library (oCERT-2015-003, BACKRONYM)
https://notcve.org/view.php?id=CVE-2015-3152
Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before 5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, aka a "BACKRONYM" attack. Oracle MySQL en versiones anteriores a 5.7.3, Oracle MySQL Connector/C (también conocido como libmysqlclient) en versiones anteriores a 6.1.3 y MariaDB en versiones anteriores a 5.5.44 utiliza la opción --ssl significa que SSL es opcional, lo que permite a atacantes man-in-the-middle suplantar servidores a través de un ataque de degradación de texto plano, también conocida como un ataque "BACKRONYM". It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the "--ssl" option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. • http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161436.html http://lists.fedoraproject.org/pipermail/package-announce/2015-July/161625.html http://mysqlblog.fivefarmers.com/2014/04/02/redefining-ssl-option http://mysqlblog.fivefarmers.com/2015/04/29/ssltls-in-5-6-and-5-5-ocert-advisory http://packetstormsecurity.com/files/131688/MySQL-SSL-TLS-Downgrade.html http://rhn.redhat.com/errata/RHSA-2015-1646.html http://rhn.redhat.com/errata/RHSA-2015-1647.html http://rhn& • CWE-295: Improper Certificate Validation •
