Description
Description
FFmpeg 6.1 through 9.0.2 contains an information disclosure vulnerability in the CamStudio decoder (libavcodec/cscd.c) that copies uninitialized heap memory into decoded frames when decompressed payloads are short. Attackers can supply a crafted AVI with a CSCD stream whose LZO or zlib frames decompress to fewer bytes than the frame size, recovering heap contents from the decoded or re-encoded output.
