Ticket #5129: libs_libmythtv_dvbrecorder.cpp-make-sure-pid-doesnt-overrun-pid_status.patch

File libs_libmythtv_dvbrecorder.cpp-make-sure-pid-doesnt-overrun-pid_status.patch, 927 bytes (added by Erik Hovland <erik@…>, 16 years ago)

check pid for 0x1fff before putting it into _pid_status

  • libs/libmythtv/dvbrecorder.cpp 

    A pid can be 0x01fff (null packet). But the pid_status array only goes to 1fff. So indexing

From: Erik Hovland <erik@hovland.org>

there is not a good idea.
