Comment 1 Alexandros Toptsoglou 2019-01-31 10:22:47 UTC
The patch for CVE-2018-20019 did not completely fix the issue. Thus a new CVE was created and more fixes[1][2][3][4] became available which when applied deal with the issue completely. 

All of our codestreams had received the patch for CVE-2018-20019 and also all of them are affected.
