🔒 fix potential panic when match finder is missing#425
Conversation
Replaced unsafe .unwrap() calls on self.mf.take() with safe checks that return a new InternalError variant. This prevents a potential Denial of Service (DoS) panic if the match finder is unexpectedly None, for example, due to a previous panic poisoning the Compressor state. Updated the return signature of Compressor::compress_to_size to support error propagation.

🎯 What: Fixed potential panics in
⚠️ Risk: A Denial of Service (DoS) vulnerability where an attacker could trigger a crash if they can induce a state where the match finder is
Compressor::compressandCompressor::compress_to_sizecaused by calling.unwrap()on a missing match finder.None(e.g., by reusing aCompressorinstance after a previous operation panicked).🛡️ Solution: Introduced a
CompressResult::InternalErrorvariant and replaced.unwrap()with safe pattern matching. Updated the public API to propagate these errors asstd::io::Error. Added a regression testtest_compressor_missing_mf.PR created automatically by Jules for task 17842979915340093213 started by @404Setup
