The tcp_illinois_info function in net/ipv4/tcp_illinois.c in the Linux kernel before 3.4.19, when the net.ipv4.tcp_congestion_control illinois setting is enabled, allows local users to cause a denial of service (divide-by-zero error and OOPS) by reading TCP stats. La función tcp_illinois_info en net/ipv4/tcp_illinois.c en el kernel de Linux antes de v3.4.19, cuando la opción net.ipv4.tcp_congestion_control illinois está habilitada, permite a usuarios locales provocar una denegación de servicio (división por cero y caída) mediante la lectura de estadísticas TCP. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=8f363b77ee4fbf7c3bbcf5ec2c5ca482d396d664 http://lists.fedoraproject.org/pipermail/package-announce/2012-November/091110.html http://rhn.redhat.com/errata/RHSA-2012-1580.html http://secunia.com/advisories/51409 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.4.19 http://www.openwall.com/lists/oss-security/2012/10/31/5 http://www.securityfocus.com/bid/56346 http://www.ubuntu.com/usn/USN- • CWE-189: Numeric Errors •

The (1) do_siocgstamp and (2) do_siocgstampns functions in net/socket.c in the Linux kernel before 3.5.4 use an incorrect argument order, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (system crash) via a crafted ioctl call. Las funciones (1) do_siocgstamp y (2) do_siocgstampns en net/socket.c en el kernel Linux antes de v3.5.4, utiliza un orden incorrecto de los argumentos, lo que podría permitir a un usuario local obtener información sensible de la memoria del kernel o provocar una denegación de servicio (caída del sistema) a través de una llamada ioctl manipulada. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ed6fe9d614fc1bca95eb8c0ccd0e92db00ef9d5d http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.5.4 http://www.openwall.com/lists/oss-security/2012/10/04/2 http://www.securityfocus.com/bid/55785 https://github.com/torvalds/linux/commit/ed6fe9d614fc1bca95eb8c0ccd0e92db00ef9d5d • CWE-399: Resource Management Errors •
