Description Vasyl Kaigorodov 2014-09-15 09:43:54 EDT 
Linux kernel built with the UDF file system support(CONFIG_UDF_FS) is vulnerable
to a crash due to stack overflow through infinite recursion. It occurs while traversing a long ICB hierarchy.

a user/program able to mount such a file system could use this flaw to crash the system kernel resulting in DoS.
