The glob implementation in tnftpd (formerly lukemftpd), as used in Apple OS X before 10.11, allows remote attackers to cause a denial of service (memory consumption and daemon outage) via a STAT command containing a crafted pattern, as demonstrated by multiple instances of the {..,..,..}/* substring.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
