CVSS: 7.8EPSS: 0%CPEs: 12EXPL: 0CVE-2016-5828 – Kernel: powerpc: tm: crash via exec system call on PPC
https://notcve.org/view.php?id=CVE-2016-5828
The start_thread function in arch/powerpc/kernel/process.c in the Linux kernel through 4.6.3 on powerpc platforms mishandles transactional state, which allows local users to cause a denial of service (invalid process state or TM Bad Thing exception, and system crash) or possibly have unspecified other impact by starting and suspending a transaction before an exec system call. La función start_thread en arch/powerpc/kernel/process.c en el kernel de Linux hasta la versión 4.6.3 en plataformas powerpc no maneja adecuadamente el estado transaccional, lo que permite a usuarios locales provocar una denegación de servicio (estado de proceso inválido o excepción TM Bad Thing y caída de sistema) o posiblemente tener otro impacto no especificado iniciando y suspendiendo una transacción antes de una llamada de sistema exec. A vulnerability in the handling of Transactional Memory on powerpc systems was found. An unprivileged local user can crash the kernel by starting a transaction, suspending it, and then calling any of the exec() class system calls. • http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00055.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://www.debian.org/security/2016/dsa-3616 http://www.openwall.com/lists/oss-security/2016/06/25/7 http://www.securityfocus.com/bid/91415 http://www.ubuntu.com/usn/USN-3070-1 http://www.ubuntu.com&# • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 0CVE-2016-5829 – kernel: Heap buffer overflow in hiddev driver
https://notcve.org/view.php?id=CVE-2016-5829
Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. Múltiples desbordamientos de buffer basado en memoria dinámica en la función hiddev_ioctl_usage en drivers/hid/usbhid/hiddev.c en el kernel de Linux hasta la versión 4.6.3 permiten a usuarios locales provocar una denegación de servicio o tener posiblemente otro impacto no especificado a través de una llamada (1) HIDIOCGUSAGES o (2) HIDIOCSUSAGES ioctl manipulada. A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93a2001bdfd5376c3dc2158653034c20392d15c5 http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00048.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716. La protección de desbordamiento en Expat es eliminada por los compiladores con ciertos ajustes de optimización, lo que permite a atacantes remotos provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de datos XML manipulados. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2015-1283 y CVE-2015-2716. • http://www.securityfocus.com/bid/91528 http://www.ubuntu.com/usn/USN-3013-1 https://bugzilla.redhat.com/show_bug.cgi?id=1344251 https://kc.mcafee.com/corporate/index?page=content&id=SB10365 https://security.gentoo.org/glsa/201701-21 https://sourceforge.net/p/expat/code_git/ci/f0bec73b018caa07d3e75ec8dd967f3785d71bde https://www.tenable.com/security/tns-2016-20 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 8.8EPSS: 95%CPEs: 10EXPL: 7CVE-2016-4971 – GNU Wget < 1.18 - Arbitrary File Upload
https://notcve.org/view.php?id=CVE-2016-4971
GNU wget before 1.18 allows remote servers to write to arbitrary files by redirecting a request from HTTP to a crafted FTP resource. GNU wget en versiones anteriores a 1.18 permite a servidores remotos escribir archivos arbitrarios redirigiendo una petición desde HTTP a una fuente FTP manipulada. It was found that wget used a file name provided by the server for the downloaded file when following a HTTP redirect to a FTP server resource. This could cause wget to create a file with a different name than expected, possibly allowing the server to execute arbitrary code on the client. GNU Wget versions prior to 1.18 suffer from an arbitrary file upload vulnerability that may allow for remote code execution. • https://www.exploit-db.com/exploits/49815 https://www.exploit-db.com/exploits/40064 https://github.com/gitcollect/CVE-2016-4971 https://github.com/mbadanoiu/CVE-2016-4971 https://github.com/dinidhu96/IT19013756_-CVE-2016-4971- http://git.savannah.gnu.org/cgit/wget.git/commit/?id=e996e322ffd42aaa051602da182d03178d0f13e1 http://lists.gnu.org/archive/html/info-gnu/2016-06/msg00004.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00043.html http://packetstormsecurity.com/files • CWE-73: External Control of File Name or Path •

https://notcve.org/view.php?id=CVE-2016-2178
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack. La función dsa_sign_setup en crypto/dsa/dsa_ossl.c en OpenSSL hasta la versión 1.0.2h no asegura correctamente la utilización de operaciones de tiempo constante, lo que facilita a usuarios locales descubrir una clave privada DSA a través de un ataque de sincronización de canal lateral. It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures. A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system. • http://eprint.iacr.org/2016/594.pdf http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org& • CWE-203: Observable Discrepancy CWE-385: Covert Timing Channel •
