CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2014-8172 – kernel: soft lockup on aio
https://notcve.org/view.php?id=CVE-2014-8172
The filesystem implementation in the Linux kernel before 3.13 performs certain operations on lists of files with an inappropriate locking approach, which allows local users to cause a denial of service (soft lockup or system crash) via unspecified use of Asynchronous I/O (AIO) operations. La implementación del sistema de fichero en el Kernel de Linux anterior a 3.13 realizar ciertas operaciones en listas de archivos con un inapropiado bloqueo, lo que permite a usuarios locales causar una denegación de servicio (bloqueo blando 'soft lockup' o caída del sistema) a través del uso de operaciones Asynchronous I/O (AIO) no especificadas. It was found that due to excessive files_lock locking, a soft lockup could be triggered in the Linux kernel when performing asynchronous I/O operations. A local, unprivileged user could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=eee5cc2702929fd41cce28058dc6d6717f723f87 http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0694.html http://www.openwall.com/lists/oss-security/2015/03/09/3 https://bugzilla.redhat.com/show_bug.cgi?id=1198503 https://github.com/torvalds/linux/commit/eee5cc2702929fd41cce28058dc6d6717f723f87 https://access.redhat.com/security/cve/CVE-2014-8172 • CWE-17: DEPRECATED: Code •

Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data. Vulnerabilidad de uso después de liberación en la función sctp_assoc_update en net/sctp/associola.c en el Kernel de Linux anterior a 3.18.8 permite a atacantes remotos causar una denegación de servicio (corrupción de bloque y pánico) o la posibilidad de tener otro impacto no especificado mediante la provocación de una colisión INIT que lleva al manejo inadecuado de datos de shared-key. A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=600ddd6825543962fb807884169e57b580dba208 http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://rhn.redhat.com/errata/RHSA-2015-0726.html http://rhn.redhat.com/errata/RHSA-2015-0751.html http://rhn.redhat.com/errata/RHSA-2015-0782.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://rhn.redhat. • CWE-416: Use After Free •

Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function. Condición de carrera en la función handle_to_path en fs/fhandle.c en el Kernel de Linux a través de 3.19.1 permite a usuarios locales evadir las restricciones del tamaño y lanzar operaciones de lectura en ubicaciones de memoria adicionales cambiando el valor de handle_bytes del manejador del archivo durante la ejecución de su función. • http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00021.html http://marc.info/?l=linux-kernel&m=142247707318982&w=2 http://www.debian.org/security/2015/dsa-3170 http://www.openwall • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
