zlib: A flaw found in zlib when compressing (not decompressing) certain inputs

An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating ex: when compressing if the input has many distant matches. For some rare inputs with a large number of distant matches crafted payloads, the buffer into which the compressed or deflated data is written...
