CVE-2010-3442

Published: 4 October 2010

Multiple integer overflows in the snd_ctl_new function in sound/core/control.c in the Linux kernel before 2.6.36-rc5-next-20100929 allow local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (1) SNDRV_CTL_IOCTL_ELEM_ADD or (2) SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl call.

From the Ubuntu Security Team

Dan Rosenberg discovered that the Sound subsystem did not correctly validate parameters. A local attacker could exploit this to crash the system, leading to a denial of service.
