Memory leak in the cuse_channel_release function in fs/fuse/cuse.c in the Linux kernel before 4.4 allows local users to cause a denial of service (memory consumption) or possibly have unspecified other impact by opening /dev/cuse many times. Fuga de memoria en la función cuse_channel_release en fs/fuse/cuse.c en el kernel de Linux en versiones anteriores a 4.4 permite a usuarios locales provocar una denegación de servicio (consumo de memoria) o posiblemente tener otro impacto no especificado abriendo /dev/cuse muchas veces. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2c5816b4beccc8ba709144539f6fdd764f8fa49c http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://www.openwall.com/lists/oss-security/2016/03/02/13 https://bugzilla.novell.com/show_bug.cgi?id=969356 https://bugzilla.redhat.com/show_bug.cgi?id=1314331 https://github.com/torvalds/linux/commit/2c5816b4beccc8ba709144539f6fdd764f8fa49c https • CWE-399: Resource Management Errors •
CVE-2016-3672 – Linux Kernel (x86) - Disable ASLR by Setting the RLIMIT_STACK Resource to Unlimited
https://notcve.org/view.php?id=CVE-2016-3672
The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. La función arch_pick_mmap_layout en arch/x86/mm/mmap.c en el kernel de Linux hasta la versión 4.5.2 no maneja de forma aleatoria el legado de la dirección base, lo que hace más fácil a usuarios locales romper las restricciones destinadas en los indicadores ADDR_NO_RANDOMIZE, y eludir el mecanismo de protección ASLR para programas setuid o setid, deshabilitando los límites de recursos del consumo de pila. A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited. • https://www.exploit-db.com/exploits/39669 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8b8addf891de8a00e4d39fc32f93f7c5eb8feceb http://hmarco.org/bugs/CVE-2016-3672-Unlimiting-the-stack-not-longer-dis http://hmarco.org/bugs/CVE-2016-3672-Unlimiting-the-stack-not-longer-disables-ASLR.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182524.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/open • CWE-254: 7PK - Security Features CWE-341: Predictable from Observable State •
CVE-2016-2085
https://notcve.org/view.php?id=CVE-2016-2085
The evm_verify_hmac function in security/integrity/evm/evm_main.c in the Linux kernel before 4.5 does not properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel attack. La función evm_verify_hmac en security/integrity/evm/evm_main.c en el kernel de Linux en versiones anteriores a 4.5 no copia correctamente los datos, lo que facilita a usuarios locales falsificar los valores MAC a través de un ataque de tiempo side-chanel. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=613317bd212c585c20796c10afe5daaa95d4b0a1 http://www.ubuntu.com/usn/USN-2946-1 http://www.ubuntu.com/usn/USN-2946-2 http://www.ubuntu.com/usn/USN-2947-1 http://www.ubuntu.com/usn/USN-2947-2 http://www.ubuntu.com/usn/USN-2947-3 http://www.ubuntu.com/usn/USN-2948-1 http://www.ubuntu.com/usn/USN-2948-2 http://www.ubuntu.com/usn/USN-2949-1 https://bugzilla.redhat.com/show • CWE-19: Data Processing Errors •
CVE-2016-2383
https://notcve.org/view.php?id=CVE-2016-2383
The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions. La función adjust_branches en kernel/bpf/verifier.c en el kernel de Linux en versiones anteriores a 4.5 no tiene en cuenta el delta en el caso de salto de retroceso, lo que permite a usuarios locales obtener información sensible del kernel de memoria creando un filtro de paquetes y posteriormente cargando instrucciones BPF manipuladas. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a1b14d27ed0965838350f1377ff97c93ee383492 http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://www.openwall.com/lists/oss-security/2016/02/14/1 http://www.ubuntu.com/usn/USN-2947-1 http://www.ubuntu.com/usn/USN-2947-2 http://www.ubuntu.com/usn/USN-2947-3 https://bugzilla.redhat.com/show_bug.cgi?id=1308452 https://github.com/torvalds/linux/commit/a1b14d27ed0965838350f1377ff97c93ee3834 •
CVE-2016-2847 – kernel: pipe: limit the per-user amount of pages allocated in pipes
https://notcve.org/view.php?id=CVE-2016-2847
fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes. fs/pipe.c en el kernel de Linux antes de 4.5 no limita la cantidad de datos no leídos en las tuberías, lo que permite a los usuarios locales provocar una denegación de servicio (consumo de memoria) creando muchas tuberías con tamaños no predeterminados. It is possible for a single process to cause an OOM condition by filling large pipes with data that are never read. A typical process filling 4096 pipes with 1 MB of data will use 4 GB of memory and there can be multiple such processes, up to a per-user-limit. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=759c01142a5d0f364a462346168a56de28a80f52 http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.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/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
