indeo4: Decode all or nothing of a band header.
This avoids inconsistent value combinations. Alternatively it would be possible to add more checks and careful use of temporary variables, but my try of this quickly seemed to become a rather large change. The disadvantage of this, is that the struct is copied back and forth. Fixes: index 6 out of bounds for type 'const uint16_t [5][16]' Fixes: 6557/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_INDEO4_fuzzer-4787296550256640 Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit 10c8521265da86118597336c5589e26de377a374) Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
