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.

Updated kernel packages that fix three security issues and several bugs are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel pa ...

An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space.

An out-of-bounds write flaw was found in the way the Apple Magic Mouse/Trackpad multi-touch driver handled Human Interface Device (HID) reports with an invalid size. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.An information leak flaw was found in the way the Linux kernel handled media device enumer ...

An integer overflow flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use this flaw to crash the system.
