Description Prasad J Pandit 2015-06-04 12:43:12 UTC
Linux kernel built with the UDF file system(CONFIG_UDF_FS) support is
vulnerable to a crash. It could occur while reading from a corrupted/malicious
udf file system image.

An unprivileged user could use this flaw to crash the kernel resulting in DoS.

Comment 2 Prasad J Pandit 2015-06-05 06:23:18 UTC
This has been rated as having Moderate security impact and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.

Comment 3 Prasad J Pandit 2015-06-05 06:23:53 UTC
Acknowledgement:

Red Hat would like to thank Carl H Lunde for reporting this issue

Comment 5 Wade Mealing 2015-07-16 01:17:23 UTC
Mitigation:

The UDF filesystem is enabled via loading the UDF kernel module.  The kernel module can be prevented from loading via blacklisting see https://access.redhat.com/solutions/41278 for more information.
