From 3e6e1b2097e8960b0f6ca9b3cec6638d5b6edf49 Mon Sep 17 00:00:00 2001 From: Martin Storsjo Date: Tue, 8 Oct 2019 15:10:32 +0300 Subject: [PATCH] Revert "Reapply: Avoid reading out of bounds due to too large aaIidIndexMapped" This reverts commit 28fdc28ec436ceafb11ceb6a354e9916c5265981. It seems like this isn't needed any longer on the latest upstream version. --- libSBRdec/src/psdec.cpp | 15 +++++---------- 1 file changed, 5 insertions(+), 10 deletions(-) diff --git a/libSBRdec/src/psdec.cpp b/libSBRdec/src/psdec.cpp index b31b310..1f8bd25 100644 --- a/libSBRdec/src/psdec.cpp +++ b/libSBRdec/src/psdec.cpp @@ -325,7 +325,7 @@ void initSlotBasedRotation( int env, int usb) { INT group = 0; INT bin = 0; - INT noIidSteps, noFactors; + INT noIidSteps; FIXP_SGL invL; FIXP_DBL ScaleL, ScaleR; @@ -337,11 +337,9 @@ void initSlotBasedRotation( if (h_ps_d->bsData[h_ps_d->processSlot].mpeg.bFineIidQ) { PScaleFactors = ScaleFactorsFine; /* values are shiftet right by one */ noIidSteps = NO_IID_STEPS_FINE; - noFactors = NO_IID_LEVELS_FINE; } else { PScaleFactors = ScaleFactors; /* values are shiftet right by one */ noIidSteps = NO_IID_STEPS; - noFactors = NO_IID_LEVELS; } /* dequantize and decode */ @@ -360,13 +358,10 @@ void initSlotBasedRotation( /* ScaleR and ScaleL are scaled by 1 shift right */ - ScaleL = ScaleR = 0; - if (noIidSteps + h_ps_d->specificTo.mpeg.pCoef->aaIidIndexMapped[env][bin] >= 0 && noIidSteps + h_ps_d->specificTo.mpeg.pCoef->aaIidIndexMapped[env][bin] < noFactors) - ScaleR = PScaleFactors[noIidSteps + h_ps_d->specificTo.mpeg.pCoef - ->aaIidIndexMapped[env][bin]]; - if (noIidSteps - h_ps_d->specificTo.mpeg.pCoef->aaIidIndexMapped[env][bin] >= 0 && noIidSteps - h_ps_d->specificTo.mpeg.pCoef->aaIidIndexMapped[env][bin] < noFactors) - ScaleL = PScaleFactors[noIidSteps - h_ps_d->specificTo.mpeg.pCoef - ->aaIidIndexMapped[env][bin]]; + ScaleR = PScaleFactors[noIidSteps + h_ps_d->specificTo.mpeg.pCoef + ->aaIidIndexMapped[env][bin]]; + ScaleL = PScaleFactors[noIidSteps - h_ps_d->specificTo.mpeg.pCoef + ->aaIidIndexMapped[env][bin]]; AlphasValue = 0; if (h_ps_d->specificTo.mpeg.pCoef->aaIccIndexMapped[env][bin] >= 0)
