Heap-based Buffer Overflow Affecting kernel-rt-debug package, versions *

Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug package and not the kernel-rt-debug package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The UDF filesystem implementation in the Linux kernel before 3.18.2 does not validate certain lengths, which allows local users to cause a denial of service (buffer over-read and system crash) via a crafted filesystem image, related to fs/udf/inode.c and fs/udf/symlink.c.
