Target Milestone: ---
Classification: Other
When reading a specially crafted TAR archive an Apache Ant build can be made to
allocate large amounts of memory that finally leads to an out of memory error,
even for small inputs. This can be used to disrupt builds using Apache Ant.
Apache Ant prior to 1.9.16 and 1.10.11 were affected.
