: Instead of a "fat" binary, target your specific CPU to avoid including unused SIMD optimizations.
: libvpx includes optimizations for various CPU architectures (like x86, ARM, and different SIMD extensions like AVX2 or NEON). Including all these can swell the binary. bloat libvpx
While often referred to colloquially as resulting from "bloat" or code complexity, the specific issue here is a logic error in handling multi-instance initialization. The vpx_codec_enc_init_multi function is intended to parallelize encoding tasks. The complexity of managing multiple instances introduced a logic path where input validation was overlooked. This highlights the risks associated with expanding API surfaces without rigorous boundary checking on every parameter. : Instead of a "fat" binary, target your
The vulnerability impacts any software dynamically linking against a vulnerable version of libvpx . Major impacts include: While often referred to colloquially as resulting from
The keyword refers to the perceived or actual inefficiencies, excessive binary size, and resource consumption of the libvpx library, the reference implementation for the VP8 and VP9 video codecs. While highly efficient at compression, libvpx is often criticized for its slow encoding speeds and complex dependency management, which can lead to "bloat" in modern software pipelines. 1. Understanding Bloat in libvpx Software bloat in libvpx typically manifests in three ways:
