Description Doran Moppert 2016-06-22 03:28:00 UTC
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.
