Details

The compression and decompression function used mem:uninitialized to create an array of uninitialized values, to later write values into it. This later leads to reads from uninitialized memory.

The flaw was corrected in commit b633bf265e41c60dfce3be7eac4e4dd5e18d06cf by using a heap-allocated Vec and removing out use of mem::uninitialized. The fix was released in v0.3.2 and v1.0.0

Subsequently the crate was deprecated and its use is discouraged.
