* x86/cfhddsp: zero extend int argumentsJames Almer2020-08-28
| | | | | | | | | | if taken from stack, they may have garbage in the upper bits otherwise. Also, there are only 8 arguments, so don't attempt to load 11. Fixes SIGSEV crashes in some targets. Reviewed-by: durandal_1707 Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/tiff: Restrict tag order based on specificationMichael Niedermayer2020-08-26
| | | | | | | | | | | | | | | | | | | | "The entries in an IFD must be sorted in ascending order by Tag. Note that this is not the order in which the fields are described in this document." This way various dimensions, sample and bit sizes cannot be changed at arbitrary times which reduces the potential for bugs. The tag reading code also on various places assumes that numerically previous tags have already been parsed, so this needs to be enforced one way or another. If this commit causes problems with real world files which are not easy to fix then some other form of checks are needed to ensure the various dependencies in the tag reading are not violated.

* avcodec/cbs_av1: fix setting FrameWidth in frame_size_with_refs()James Almer2020-08-25
| | | | | | | | | | | | | | | | Section 5.9.7 of the spec states UpscaledWidth = RefUpscaledWidth[ ref_frame_idx[ i ] ] FrameWidth = UpscaledWidth FrameHeight = RefFrameHeight[ ref_frame_idx[ i ] ] RenderWidth = RefRenderWidth[ ref_frame_idx[ i ] ] RenderHeight = RefRenderHeight[ ref_frame_idx[ i ] ] Meaning FrameWidth must not be set to RefFrameWidth[ ref_frame_idx[ i ] ] like we're currently doing.
