https://notcve.org/view.php?id=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. La función raw_cmd_copyin en drivers/block/floppy.c en el kernel de Linux hasta 3.14.3 no maneja debidamente condiciones de error durante el procesado de una llamada FDRAWCMD ioctl, lo que permite a usuarios locales provocar operaciones kfree y ganar privilegios mediante el aprovechamiento de acceso de escritura hacia un dispositivo /dev/fd. A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important) It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ef87dbe7614341c2e7bfe8d32fcb7028cc97442c http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3043.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00012.html http://rhn.redhat.com/errata/RHSA-2014-0800.html http://rhn.redhat.com/errata/RHSA-2014-0801.html http://secunia.com • CWE-754: Improper Check for Unusual or Exceptional Conditions •
