NVD Description
Note: Versions mentioned in the description apply only to the upstream libjpeg package and not the libjpeg package as distributed by Ubuntu.
libjpeg 1.63 has a heap-based buffer over-read in HierarchicalBitmapRequester::FetchRegion in hierarchicalbitmaprequester.cpp because the MCU size can be different between allocation and use.
