CVSS: 7.5EPSS: 0%CPEs: 14EXPL: 2CVE-2016-9579 – ceph: Object Gateway server DoS by sending invalid cross-origin HTTP request
https://notcve.org/view.php?id=CVE-2016-9579
A flaw was found in the way Ceph Object Gateway would process cross-origin HTTP requests if the CORS policy was set to allow origin on a bucket. A remote unauthenticated attacker could use this flaw to cause denial of service by sending a specially-crafted cross-origin HTTP request. Ceph branches 1.3.x and 2.x are affected. Se ha encontrado un error en la forma en la que Ceph Object Gateway procesa peticiones HTTP cross-origin si la política CORS está configurada para permitir el origen en un bucket. Un atacante remoto no autenticado podría utilizar este problema para provocar una denegación de servicio (DoS) mediante el envío de una petición HTTP cross-origin especialmente manipulada. • http://rhn.redhat.com/errata/RHSA-2016-2954.html http://rhn.redhat.com/errata/RHSA-2016-2956.html http://rhn.redhat.com/errata/RHSA-2016-2994.html http://rhn.redhat.com/errata/RHSA-2016-2995.html http://tracker.ceph.com/issues/18187 http://www.securityfocus.com/bid/94936 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-9579 https://access.redhat.com/security/cve/CVE-2016-9579 https://bugzilla.redhat.com/show_bug.cgi?id=1403245 • CWE-20: Improper Input Validation •
CVSS: 7.8EPSS: 0%CPEs: 17EXPL: 0CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
CVSS: 8.1EPSS: 97%CPEs: 68EXPL: 10CVE-2015-7547 – glibc - 'getaddrinfo' Stack Buffer Overflow (PoC)
https://notcve.org/view.php?id=CVE-2015-7547
Multiple stack-based buffer overflows in the (1) send_dg and (2) send_vc functions in the libresolv library in the GNU C Library (aka glibc or libc6) before 2.23 allow remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted DNS response that triggers a call to the getaddrinfo function with the AF_UNSPEC or AF_INET6 address family, related to performing "dual A/AAAA DNS queries" and the libnss_dns.so.2 NSS module. Múltiples desbordamientos de buffer basado en pila en las funciones (1) send_dg y (2) send_vc en la librería libresolv en la librería GNU C (también conocida como glibc o libc6) en versiones anteriores a 2.23 permiten a atacantes remotos causar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de una respuesta DNS manipulada que desencadenan una llamada a la función getaddrinfo con la familia de direcciones AF_UNSPEC o AF_INET6, en relación con la ejecución de "consultas duales A/AAAA DNS" y el módulo libnss_dns.so.2 NSS. A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. • https://www.exploit-db.com/exploits/39454 https://www.exploit-db.com/exploits/40339 https://github.com/fjserna/CVE-2015-7547 https://github.com/cakuzo/CVE-2015-7547 https://github.com/Stick-U235/CVE-2015-7547-Research https://github.com/t0r0t0r0/CVE-2015-7547 https://github.com/babykillerblack/CVE-2015-7547 https://github.com/Amilaperera12/Glibc-Vulnerability-Exploit-CVE-2015-7547 https://github.com/miracle03/CVE-2015-7547-master https://github.com/bluebluelan/CVE-2015-7547&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

The Linux kernel, as used in Red Hat Enterprise Linux 7, kernel-rt, and Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended securelevel/secureboot restrictions by leveraging improper handling of secure_boot flag across kexec reboot. El kernel de Linux, tal y como se emplea en Red Hat Enterprise Linux 7, kernel-rt y Enterprise MRG 2 y cuando se emplea con UEFI Secure Boot habilitado, permite que usuarios locales omitan las restricciones securelevel/secureboot previstas aprovechando la gestión incorrecta de la marca secure_boot cuando se reinicia kexec. A flaw was found in the way the Linux kernel handled the securelevel functionality after performing a kexec operation. A local attacker could use this flaw to bypass the security mechanism of the securelevel/secureboot combination. • http://rhn.redhat.com/errata/RHSA-2015-2152.html http://rhn.redhat.com/errata/RHSA-2015-2411.html http://www.openwall.com/lists/oss-security/2015/10/15/6 http://www.securityfocus.com/bid/77097 https://bugzilla.redhat.com/show_bug.cgi?id=1272472 https://github.com/mjg59/linux/commit/4b2b64d5a6ebc84214755ebccd599baef7c1b798 https://access.redhat.com/security/cve/CVE-2015-7837 • CWE-254: 7PK - Security Features CWE-456: Missing Initialization of a Variable •
