CVSS: 6.2EPSS: 0%CPEs: 4EXPL: 0CVE-2013-4312 – kernel: File descriptors passed over unix sockets are not properly accounted
https://notcve.org/view.php?id=CVE-2013-4312
The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c. El kernel de Linux en versiones anteriores a 4.4.1 permite a usuarios locales eludir los limites de descriptor de fichero y provocar una denegación de servicio (consumo de memoria) enviando cada descriptor a través de un socket UNIX antes de cerrarlo, relacionado con net/unix/af_unix.c y net/unix/garbage.c. It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=712f4aad406bb1ed67f3f98d04c044191f0ff593 http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176464.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2016/dsa-3448 http://www.debian.or • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-400: Uncontrolled Resource Consumption •

Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call. Condición de carrera en la función tty_ioctl en drivers/tty/tty_io.c en el kernel de Linux hasta la versión 4.4.1 permite a usuarios locales obtener información sensible de la memoria del kernel o provocar una denegación de servicio (uso después de liberación y caída de aplicación) al hacer una llamada ioctl TIOCGETD ioctl durante el procesamiento de una llamada ioctl TIOCSETD. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5c17c861a357e9458001f021a7afa7aab9937439 http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176464.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel before 4.3.4 does not properly use a semaphore, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls. La función keyctl_read_key en security/keys/keyctl.c en el kernel de Linux en versiones anteriores a 4.3.4 no utiliza adecuadamente un semáforo, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL y caída del sistema) o posiblemente tiene otro impacto no especificado a través de una aplicación manipulada que aprovecha una condición de carrera entre llamadas keyctl_revoke y keyctl_read. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b4a1b4f5047e4f54e194681125c74c0aa64d637d http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00038.html http://www.debian.org/security/2016/dsa-3434 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.3.4 http://www.securityfocus.com/bid/79903 http:/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states "there is no kernel bug here. ** DISPUTADA ** kernel/ptrace.c en el kernel de Linux hasta la versión 4.4.1 no maneja correctamente el mapeo uid y gid, lo que permite a usuarios locales obtener privilegios estableciendo un espacio de nombres de usuario, a la espera de un proceso root para entrar ese espacio de nombres con un uid o gid inseguro, y después utilizando la llamada al sistema ptrace.
