The rtp_packetize_xiph_config function in modules/stream_out/rtpfmt.c in VideoLAN VLC media player before 2.1.6 uses a stack-allocation approach with a size determined by arbitrary input data, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted length value.
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.
