Memory corruption via immutable packet mutation
Published Sep 2, 2025 · Updated Sep 2, 2025
Use-after-free in rust-ffmpeg 0.3.0 allows remote attackers to crash a consuming process or corrupt memory during packet interleaving. The write_interleaved method accepts an immutable packet reference but passes its pointer to av_interleaved_write_frame, which mutates and clears the packet while Rust still treats it as shared. Exploitation requires the consuming code to access the packet afterward, triggering undefined behavior within that process.
