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-2015-3456 – QEMU - Floppy Disk Controller (FDC) (PoC)
https://notcve.org/view.php?id=CVE-2015-3456
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. Floppy Disk Controller (FDC) en QEMU, utilizado en Xen 4.5.x y anteriores y KVM, permite a usuarios locales invitados causar una denegación de servicio (escritura fuera de rango y caída del invitado) o posiblemente ejecutar código arbitrario a través de (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, u otros comandos sin especificar, también conocido como VENOM. An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. • https://www.exploit-db.com/exploits/37053 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=e907746266721f305d67bc0718795fedee2e824c http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10693 http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158072.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00014.html http:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
