  "title": "rust-lz4-flex: lz4_flex is a pure Rust implementation of LZ4 compression/decompression",
  "description": "lz4_flex is a pure Rust implementation of LZ4 compression/decompression. In versions 0.11.5 and below, and 0.12.0,  decompressing invalid LZ4 data can leak sensitive information from uninitialized memory or from previous decompression operations. The library fails to properly validate offset values during LZ4 \u0022match copy operations,\u0022 allowing out-of-bounds reads from the output buffer. The block-based API functions (\u0060decompress_into\u0060, \u0060decompress_into_with_dict\u0060, and others when \u0060safe-decode\u0060 is disabled) are affected, while all frame APIs are unaffected. The impact is potential exposure of sensitive data and secrets through crafted or malformed LZ4 input. This issue has been fixed in versions 0.11.6 and 0.12.1.",
