zlib-rs 0.6.7 Released With LoongArch LSX Optimizations, Use-After-Free Fix Written by Michael Larabel in Free Software on 3 August 2026 at 09:19 AM EDT. Add A Comment zlib-rs 0.6.7 is out today as the newest version of this "safer zlib" implementation making use of the Rust programming language and aiming to deliver performance on-par with zlib-ng. The zlib-rs 0.6.7 release fixes a new use-after-free vulnerability discovered in its codebase. This ticket from yesterday outlines the use-after-free condition in Deflate::compress_uninit along with a proof of concept example. The PoC can trigger the UAF even with forbidding any unsafe Rust features in the code. The other big focus with zlib-rs 0.6.7 is on shipping more LoongArch64 LSX optimizations for that Loongson SIMD eXtension.
