CVE-2014-4656

Published: 03 July 2014

Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function.

From the Ubuntu security team

An integer overflow flaw was discovered in the control implementation of the Advanced Linux Sound Architecture (ALSA). A local user could exploit this flaw to cause a denial of service (system crash).
