CVE-2013-2930 – kernel: perf/ftrace: insufficient check in perf_trace_event_perm()
https://notcve.org/view.php?id=CVE-2013-2930
The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application. La función perf_trace_event_perm en kernel/trace/trace_event_perf.c en el kernel Linux anteriores 3.12.2 no restringe apropiadamente el acceso al subsistema perf, lo que permite a usuarios locales habilitar el seguimiento de funciones a traves de una aplicación manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=12ae030d54ef250706da5642fc7697cc60ad0df7 http://rhn.redhat.com/errata/RHSA-2014-0100.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.12.2 http://www.ubuntu.com/usn/USN-2068-1 http://www.ubuntu.com/usn/USN-2070-1 http://www.ubuntu.com/usn/USN-2071-1 http://www.ubuntu.com/usn/USN-2072-1 http://www.ubuntu.com/usn/USN-2074-1 http://www.ubuntu.com/usn/USN& • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2013-6431 – kernel: net: fib: fib6_add: potential NULL pointer dereference
https://notcve.org/view.php?id=CVE-2013-6431
The fib6_add function in net/ipv6/ip6_fib.c in the Linux kernel before 3.11.5 does not properly implement error-code encoding, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability for an IPv6 SIOCADDRT ioctl call. La función fib6_add en net/ipv6/ip6_fib.c en el kernel de Linux anterior a 3.11.5 no implementa correctamente la codificación de código de error, lo que permite a usuarios locales provocar una denegación de servicio (referencia a un puntero NULL y caída del sistema) mediante el aprovechamiento de la capacidad CAP_NET_ADMIN de una llamada IPv6 SIOCADDRT ioctl. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ae7b4e1f213aa659aedf9c6ecad0bf5f0476e1e2 http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00002.html http://rhn.redhat.com/errata/RHSA-2014-0100.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.11.5 http://www.openwall.com/lists/oss-security/2013/12/06/5 https://bugzilla.redhat.com/show_bug.cgi?id=1039054 https://github.com/torvalds/linux/commit/ae7b4e1f213aa659aedf9c6ecad0bf5f0476e1e2& • CWE-264: Permissions, Privileges, and Access Controls CWE-476: NULL Pointer Dereference •
CVE-2013-4270 – kernel: net: permissions flaw in /proc/sys/net
https://notcve.org/view.php?id=CVE-2013-4270
The net_ctl_permissions function in net/sysctl_net.c in the Linux kernel before 3.11.5 does not properly determine uid and gid values, which allows local users to bypass intended /proc/sys/net restrictions via a crafted application. La función net_ctl_permissions en net/sysctl_net.c en el kernel Linux anteriores a 3.11.5 no determina apropiadamente valores uid y gid, lo que permite a usuarios locales franquear restricciones /proc/sys/net a traves de una aplicación manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=2433c8f094a008895e66f25bd1773cdb01c91d01 http://rhn.redhat.com/errata/RHSA-2014-0100.html http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.11.5 http://www.ubuntu.com/usn/USN-2049-1 https://bugzilla.redhat.com/show_bug.cgi?id=1027752 https://github.com/torvalds/linux/commit/2433c8f094a008895e66f25bd1773cdb01c91d01 https://access.redhat.com/security/cve/CVE-2013-4270 • CWE-20: Improper Input Validation •
CVE-2013-6382
https://notcve.org/view.php?id=CVE-2013-6382
Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c. Múltiples desbordamientos de búfer en la implementación XFS del kernel de Linux hasta la versión 3.12.1 permite a usuarios locales provocar una denegación de servicio (corrupción de memoria) o posiblemente tener otro impacto sin especificar mediante el aprovechamiento de la capacidad CAP_SYS_ADMIN para una llamada ioctl en (1) XFS_IOC_ATTRLIST_BY_HANDLE o (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 con un valor de longitud manipulado, relacionado con la función xfs_attrlist_by_handle en fs/xfs/xfs_ioctl.c y la función xfs_compat_attrlist_by_handle en fs/xfs/xfs_ioctl32.c. • http://www.openwall.com/lists/oss-security/2013/11/22/5 http://www.securityfocus.com/bid/63889 http://www.spinics.net/lists/xfs/msg23343.html http://www.ubuntu.com/usn/USN-2109-1 http://www.ubuntu.com/usn/USN-2110-1 http://www.ubuntu.com/usn/USN-2113-1 http://www.ubuntu.com/usn/USN-2117-1 http://www.ubuntu.com/usn/USN-2128-1 http://www.ubuntu.com/usn/USN-2129-1 http://www.ubuntu.com/usn/USN-2135-1 http://www.ubuntu.com/u • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2013-6380
https://notcve.org/view.php?id=CVE-2013-6380
The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 3.12.1 does not properly validate a certain size value, which allows local users to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command. La función aac_send_raw_srb en drivers/scsi/aacraid/commctrl.c del kernel de Linux hasta la versión 3.12.1 no valida adecuadamente un valor de determinado tamaño, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero nulo) o posiblemente tener otro impacto sin especificar a través de una llamada ioctl FSACTL_SEND_RAW_SRB que desencadena un comando SRB manipulado. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b4789b8e6be3151a955ade74872822f30e8cd914 http://lists.opensuse.org/opensuse-security-announce/2014-02/msg00002.html http://lists.opensuse.org/opensuse-updates/2014-02/msg00045.html http://www.openwall.com/lists/oss-security/2013/11/22/5 http://www.ubuntu.com/usn/USN-2070-1 http://www.ubuntu.com/usn/USN-2075-1 http://www.ubuntu.com/usn/USN-2109-1 http://www.ubuntu.com/usn/USN-2110-1 ht • CWE-20: Improper Input Validation •
