CVE-2015-8845 – kernel: incorrect restoration of machine specific registers from userspace
https://notcve.org/view.php?id=CVE-2015-8845
The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. La función tm_reclaim_thread en arch/powerpc/kernel/process.c en el Kernel de Linux en versiones anteriores a 4.4.1 sobre plataformas powerpc no asegura que exista el modo TM suspend antes de proceder con una llamada tm_reclaim, lo que permite a usuarios locales provocar una denegación de servicio (excepción TM Bad Thing y pánico) a través de una aplicación manipulada. A flaw was found in the Linux kernel which could cause a kernel panic when restoring machine specific registers on the PowerPC platform. Incorrect transactional memory state registers could inadvertently change the call path on return from userspace and cause the kernel to enter an unknown state and crash. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7f821fc9c77a9b01fe7b1d6e72717b33d8d64142 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html 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://rhn.redhat.com/errata/RHSA-2016-258 • CWE-284: Improper Access Control CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2016-2315 – git: path_name() integer truncation and overflow leading to buffer overflow
https://notcve.org/view.php?id=CVE-2016-2315
revision.c in git before 2.7.4 uses an incorrect integer data type, which allows remote attackers to execute arbitrary code via a (1) long filename or (2) many nested trees, leading to a heap-based buffer overflow. revision.c en git en versiones anteriores a 2.7.4 utiliza un tipo de datos de entero incorrecto, lo que permite a atacantes remotos ejecutar código arbitrario a través de un (1) nombre de archivo grande o (2) muchos árboles anidados, dando lugar a un desbordamiento de buffer basado en memoria dinámica. An integer truncation flaw and an integer overflow flaw, both leading to a heap-based buffer overflow, were found in the way Git processed certain path information. A remote attacker could create a specially crafted Git repository that would cause a Git client or server to crash or, possibly, execute arbitrary code. • http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183147.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/179121.html http://lists.fedoraproject.org/pipermail/package-announce/2016-March/180763.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00061.html http://lists.opensuse.org/opensuse-security-announce • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-194: Unexpected Sign Extension •

CVE-2015-8816
https://notcve.org/view.php?id=CVE-2015-8816
The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device. La función hub_activate en drivers/usb/core/hub.c en el Kernel de Linux en versiones anteriores a 4.3.5 no mantiene correctamente una estructura de datos hub-interface, lo que permite a atacantes físicamente próximos provocar una denegación de servicio (acceso a memoria no válido y caída de sistema) o posiblemente tener otro impacto no especificado desenchufando un dispositivo hub USB. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e50293ef9775c5f1cf3fcc093037dd6a8c5684ea http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org •
CVE-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 •
