Revision 22d65765f211cc83186fd8b87521159f354c0da9 authored by Andrej Shadura on 16 September 2021, 16:33:11 UTC, committed by Jiri Kosina on 22 September 2021, 07:31:18 UTC
Since the actual_length calculation is performed unsigned, packets
shorter than 7 bytes (e.g. packets without data or otherwise truncated)
or non-received packets ("zero" bytes) can cause buffer overflow.
