lavc/vvc: Increase IntraEdgeParams buffer size The reference line buffers are used with indices in the range -MAX_TB_SIZE - 3 to refw + FFMAX(1, w/h) * ref_idx + 1, which is at most 5*MAX_TB_SIZE + 1. Fixes buffer overflows. http://fate.ffmpeg.org/report.cgi?slot=armv7-linux-gcc-9&time=20240124051736 Signed-off-by: James Almer <jamr...@gmail.com> > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=85e031d5bfa83c25e4b644e3453fe8073d959a4c --- libavcodec/vvc/vvcdsp.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/libavcodec/vvc/vvcdsp.c b/libavcodec/vvc/vvcdsp.c index c82ea7be30..56e71d5163 100644 --- a/libavcodec/vvc/vvcdsp.c +++ b/libavcodec/vvc/vvcdsp.c @@ -87,10 +87,10 @@ typedef struct IntraEdgeParams { uint8_t* left; int filter_flag; - uint16_t left_array[3 * MAX_TB_SIZE + 3]; - uint16_t filtered_left_array[3 * MAX_TB_SIZE + 3]; - uint16_t top_array[3 * MAX_TB_SIZE + 3]; - uint16_t filtered_top_array[3 * MAX_TB_SIZE + 3]; + uint16_t left_array[6 * MAX_TB_SIZE + 5]; + uint16_t filtered_left_array[6 * MAX_TB_SIZE + 5]; + uint16_t top_array[6 * MAX_TB_SIZE + 5]; + uint16_t filtered_top_array[6 * MAX_TB_SIZE + 5]; } IntraEdgeParams; #define PROF_BORDER_EXT 1 _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog To unsubscribe, visit link above, or email ffmpeg-cvslog-requ...@ffmpeg.org with subject "unsubscribe".
