Name of the Vulnerable Software and Affected Versions libfsclfs versions prior to 2018-07-25

Description The issue allows remote attackers to cause a heap-based buffer over-read via a crafted clfs file. This is due to a problem in the libfsclfs block read function in libfsclfs block.c. The vendor has disputed this issue as described in the GitHub issue comments.
