Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier might allow local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow. Desbordamiento de entero en la función _ctl_do_mpt_command en drivers/scsi/mpt2sas/mpt2sas_ctl.c en el kernel de Linux v2.6.38 y anteriores puede permitir a usuarios locales ganar privilegios o causar una denegación de servicio (corrupción de memoria) a través de una llamada ioctl especificando un valor manipulado provocando un desbordamiento de búfer basado en heap. • http://downloads.avaya.com/css/P8/documents/100145416 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://lkml.org/lkml/2011/4/5/327 http://openwall.com/lists/oss-security/2011/04/05/32 http://openwall.com/lists/oss-security/2011/04/06/2 http://rhn.redhat.com/errata/RHSA-2011-0833.html http://secunia.com/advisories/46397 http://www.securityfocus.com/archive/1/520102/100/0/threaded http://www.securityfocus.com/bid/47185 http: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-189: Numeric Errors •
