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. 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://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-19: Data Processing Errors CWE-626: Null Byte Interaction Error (Poison Null Byte) •
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 •
CVE-2014-8171 – kernel: memcg: OOM handling DoS
https://notcve.org/view.php?id=CVE-2014-8171
The memory resource controller (aka memcg) in the Linux kernel allows local users to cause a denial of service (deadlock) by spawning new processes within a memory-constrained cgroup. El controlador de recursos de memoria (también conocido como memcg) en el kernel de Linux permite que usuarios locales provoquen una denegación de servicio (deadlock) generando nuevos procesos en un cgroup con límite de memoria. It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. • http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat.com/errata/RHSA-2015-2152.html http://rhn.redhat.com/errata/RHSA-2015-2411.html http://rhn.redhat.com/errata/RHSA-2016-0068.html http://www.securityfocus.com/bid/74293 https://bugzilla.redhat.com/show_bug.cgi?id=1198109 https://access.redhat.com/security/cve/CVE-2014-8171 • CWE-399: Resource Management Errors CWE-833: Deadlock •
CVE-2015-3330 – php: pipelined request executed in deinitialized interpreter under httpd 2.4
https://notcve.org/view.php?id=CVE-2015-3330
The php_handler function in sapi/apache2handler/sapi_apache2.c in PHP before 5.4.40, 5.5.x before 5.5.24, and 5.6.x before 5.6.8, when the Apache HTTP Server 2.4.x is used, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via pipelined HTTP requests that result in a "deconfigured interpreter." La función php_handler en sapi/apache2handler/sapi_apache2.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, cuando Apache HTTP Server 2.4.x está utilizado, permite a atacantes remotos causar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de solicitudes HTTP segmentadas que resultan en un 'interprete desconfigurado.' A flaw was found in the way the PHP module for the Apache httpd web server handled pipelined requests. A remote attacker could use this flaw to trigger the execution of a PHP script in a deinitialized interpreter, causing it to crash or, possibly, execute arbitrary code. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=809610f5ea38a83b284e1125d1fff129bdd615e7 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.apple.com/archives/security-announce/2015/Sep/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00005.html http://openwall.com/lists/oss-security/2015/04/17/7 http://php.net/ChangeLog-5.php http://rhn.redhat.com • CWE-20: Improper Input Validation CWE-665: Improper Initialization •
