Description

This update for atftp fixes the following issues :

Security issues fixed :

CVE-2019-11366: Fixed a denial of service caused by a NULL pointer dereference because thread_list_mutex was not locked (bsc#1133145).

CVE-2019-11365: Fixed a buffer overflow which could lead to remote code execution caused by an insecure use of strncpy() (bsc#1133114).
