2020-05-20avfilter/vf_dedot: Fix leak of AVFrame if making it writable failsAndreas Rheinhardt
Even in this scenario, the frame still contains references to data that won't be freed if the frame isn't unreferenced. And the AVFrame itself will leak, too. Fixes Coverity issue #1441422. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 212077eda46c4c3eb644774d2b1ccbeb3e322fff)
2020-05-20avfilter/vf_paletteuse: Fix potential double-free of AVFrameAndreas Rheinhardt
apply_palette() would free an AVFrame given to it only via an AVFrame * (and not via AVFrame **) in three of its four exists (namely in the normal path and in two error paths). So upon error the caller has no way to know whether the frame has already been freed or not; load_apply_palette(), the only caller, opted to free the frame in this scenario. This commit changes this by making apply_palette not freeing the frame at all, which is left to load_apply_palette(). Fixes Coverity issue #1452434.

2020-05-20avfilter/vf_unsharp: Don't dereference NULLAndreas Rheinhardt
The unsharp filter uses an array of arrays of uint32_t, each of which is separately allocated. These arrays also need to freed separately; but before doing so, one needs to check whether the array of arrays has actually been allocated, otherwise one would dereference a NULL pointer. This fixes #8408. Furthermore, the array of arrays needs to be zero-initialized so that no uninitialized pointer will be freed in case an allocation of one of the individual arrays fails.
