Description Agostino Sarubbo gentoo-dev 2014-05-12 07:34:17 UTC 
CVE-2014-1737 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-1737):
  The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel 
  through 3.14.3 does not properly handle error conditions during processing 
  of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations 
  and gain privileges by leveraging write access to a /dev/fd device.
