XZ Utils provide a general-purpose data-compression library plus command-line tools. Prior to version 5.8.3, if lzma index decoder() was used to decode an Index that contained no Records, the resulting lzma index was left in a state where where a subsequent lzma index append() would allocate too little memory, and a buffer overflow would occur. This issue has been patched in version 5.8.3.
