Comment 1 Andrej Nemec 2019-01-31 13:44:25 UTC

Created freerdp tracking bugs for this issue:

Affects: epel-6 [bug 1671370]

Comment 3 Riccardo Schirone 2019-02-28 15:36:02 UTC

Statement:

This issue did not affect the versions of freerdp as shipped with Red Hat Enterprise Linux 6 and 7 as they did not include the vulnerable code.
