Subject: avcodec/hevcdec: fix segfault on invalid film grain metadata
|

References: CVE-2024-32228

References: bsc#1227277
|

Upstream: Backport from upstream
|
||||
|
||||
Invalid input files may contain film grain metadata which survives
|
||||
ff_h274_film_grain_params_supported() but does not pass
|
||||
av_film_grain_params_select(), leading to a SIGSEGV on hevc_frame_end().
|
||||
|
||||
Fix this by duplicating the av_film_grain_params_select() check at frame
|
||||
init time.
|
||||
|
||||
An alternative solution here would be to defer the incompatibility check
|
||||
to hevc_frame_end(), but this has the downside of allocating a film
|
||||
grain buffer even when we already know we can't apply film grain.
