Description Agostino Sarubbo gentoo-dev 2013-11-25 19:50:11 UTC
From ${URL} :

Linux kernel built with a Adaptec RAID controllers support(CONFIG_SCSI_AACRAID)
is vulnerable to a invalid pointer dereference flaw. It could occur while doing an ioctl(2) call 
with a FSACTL_SEND_RAW_SRB command. A user would need to have
CAP_SYS_ADMIN privileges to perform such call.

A privileged(CAP_SYS_ADMIN) user/program could use this flaw to crash the kernel
resulting in DoS.

CVE-2013-6380 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-6380):
  The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the
  Linux kernel through 3.12.1 does not properly validate a certain size value,
  which allows local users to cause a denial of service (invalid pointer
  dereference) or possibly have unspecified other impact via an
  FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command.
