Original description

The description as published by the source.

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.19, decoder_context::decode_slice_unit_tiles (libde265/decctx.cc:920) reads pps.CtbAddrRStoTS[ctbAddrRS] at line 966 where ctbAddrRS = ctbY * ctbsWidth + ctbX is computed from PPS-supplied colBd[]/rowBd[] arrays without validating the result against CtbAddrRStoTS.size() == sps->PicSizeInCtbsY. A malformed PPS that passes set_derived_values but encodes geometry inconsistent with the SPS produces a ctbAddrRS past the allocation, causing a 4-byte heap-buffer-overflow READ. Version 1.0.19 fixes the issue.
