A flaw has been found in libretro RetroArch 1.18.0/1.19.0/1.20.0. This affects the function filestream_vscanf of the file libretro-common/streams/file_stream.c. This manipulation causes out-of-bounds read. The attack needs to be launched locally. Upgrading to version 1.21.0 mitigates this issue. It is recommended to upgrade the affected component.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
