Description cilly 2009-11-19 19:42:59 UTC 
DESCRIPTION:
A vulnerability has been reported in the Linux Kernel, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) and potentially gain escalated privileges.

The vulnerability is caused due to an array indexing error within the
"gdth_read_event()" function in drivers/scsi/gdth.c, which can be
exploited by sending a specially crafted IOCTL to the driver.

SOLUTION:
Fixed in the GIT repository.

CVE-2009-3080 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3080):
  Array index error in the gdth_read_event function in
  drivers/scsi/gdth.c in the Linux kernel before 2.6.32-rc8 allows
  local users to cause a denial of service or possibly gain privileges
  via a negative event index in an IOCTL request.

@Kernel: Please back-port this issue in the next 2.6.31 release.
