A memory leak was discovered in libarchive in the TAR format parser. Cleanup code in the TAR parser was attached at the wrong point, allowing a small amount of memory to be leaked for each TAR file processed. The vulnerable code was never in a released version; it was introduced and fixed between v3.1.2 and v3.2.0.
