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. (CVE-2014-9420)


A local authenticated attacker may cause a denial-of-service (DoS) to the system by using a specially crafted ISO image.

If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists.

F5 responds to vulnerabilities in accordance with the Severity values published in the previous table. The Severity values and other security vulnerability parameters are defined in K4602: Overview of the F5 security vulnerability response policy.

To mitigate this vulnerability for affected F5 products, you should permit management access to F5 products only over a secure network, and limit shell access to only trusted users.
