CVE-2011-1477

Published: 25 March 2011

Multiple array index errors in sound/oss/opl3.c in the Linux kernel before 2.6.39 allow local users to cause a denial of service (heap memory corruption) or possibly gain privileges by leveraging write access to /dev/sequencer.

From the Ubuntu Security Team

Dan Rosenberg reported errors in the kernel's OSS (Open Sound System) driver for Yamaha FM synthesizer chips. A local user can exploit this to cause memory corruption, causing a denial of service or privilege escalation.

Notes

Author	Note
jdstrand	requires /dev/sequencer and OSS (not ALSA)
