Upgrade RHEL:7 kernel-debug to version 0:3.10.0-229.7.2.el7 or higher.
This issue was patched in RHSA-2015:1137.

NVD Description

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

The rock_continue function in fs/isofs/rock.c in the Linux kernel through 3.18.1 does not restrict the number of Rock Ridge continuation entries, which allows local users to cause a denial of service (infinite loop, and system crash or hang) via a crafted iso9660 image.
