CVE-2014-0196 – Linux Kernel Race Condition Vulnerability
https://notcve.org/view.php?id=CVE-2014-0196
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings. La función n_tty_write en drivers/tty/n_tty.c en el kernel de Linux hasta 3.14.3 no maneja debidamente acceso al controlador tty en el caso 'LECHO & !OPOST', lo que permite a usuarios locales causar una denegación de servicio (consumo de memoria y caída de sistema) o ganar privilegios mediante la provocación de una condición de carrera involucrando operaciones de lectura y escritura con cadenas largas. Linux Kernel contains a race condition vulnerability within the n_tty_write function that allows local users to cause a denial-of-service (DoS) or gain privileges via read and write operations with long strings. • https://www.exploit-db.com/exploits/33516 https://github.com/tempbottle/CVE-2014-0196 https://github.com/SunRain/CVE-2014-0196 http://bugzilla.novell.com/show_bug.cgi?id=875690 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4291086b1f081b869c6d79e5b7441633dc3ace00 http://linux.oracle.com/errata/ELSA-2014-0771.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg0001 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2014-0181 – kernel: net: insufficient permision checks of netlink messages
https://notcve.org/view.php?id=CVE-2014-0181
The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program. La implementación Netlink en el kernel de Linux hasta 3.14.1 no proporciona un mecanismo para autorizar operaciones socket basadas en el abridor de un socket, lo que permite a usuarios locales evadir restricciones de acceso y modificar configuraciones de red mediante el uso de un socket Netlink para (1) stdout o (2) stderr de un programa setuid. It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. • http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://marc.info/?l=linux-netdev&m=139828832919748&w=2 http://rhn.redhat.com/errata/RHSA-2014-1959.html http://www.open • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2014-0101 – kernel: net: sctp: null pointer dereference when processing authenticated cookie_echo chunk
https://notcve.org/view.php?id=CVE-2014-0101
The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk. La función sctp_sf_do_5_1D_ce en net/sctp/sm_statefuns.c en el kernel de Linux hasta la versión 3.13.6 no valida ciertos campos auth_enable y auth_capable antes de hacer una llamada sctp_sf_authenticate, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída del sistema) a través de un SCTP handshake con un fragmento INIT modificado y un fragmento AUTH manipulado anterior a un fragmento COOKIE_ECHO. A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ec0223ec48a90cb605244b45f7c62de856403729 http://rhn.redhat.com/errata/RHSA-2014-0328.html http://rhn.redhat.com/errata/RHSA-2014-0419.html http://rhn.redhat.com/errata/RHSA-2014-0432.html http://secunia.com/advisories/59216 http://support.f5.com/kb/en-us/solutions/public/15000/300/sol15317.html http://www.openwall.com/lists/oss-security/2014/03/04/6 http://www.securityfocus.com/bid/65943 h • CWE-476: NULL Pointer Dereference •
CVE-2014-0069 – kernel: cifs: incorrect handling of bogus user pointers during uncached writes
https://notcve.org/view.php?id=CVE-2014-0069
The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer. La función cifs_iovec_write en fs/cifs/file.c en el kernel de Linux hasta 3.13.5 no maneja debidamente operaciones de escritura no en caché que copian menos bytes de los solicitados, lo que permite a usuarios locales obtener información sensible de la memoria del kernel, causar una denegación de servicio (corrupción de memoria y caída del sistema) o posiblemente ganar privilegios a través de una llamada al sistema writev con un puntero manipulado. • http://article.gmane.org/gmane.linux.kernel.cifs/9401 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=5d81de8e8667da7135d3a32a964087c0faf5483f http://lists.opensuse.org/opensuse-security-announce/2014-03/msg00026.html http://rhn.redhat.com/errata/RHSA-2014-0328.html http://www.openwall.com/lists/oss-security/2014/02/17/4 http://www.securityfocus.com/bid/65588 https://bugzilla.redhat.com/show_bug.cgi?id=1064253 https://github.com/torvalds/linux/comm • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
