Description:

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.


Mitigation:

Apache Ant 1.9.x users should upgrade to 1.9.16 or later.
Apache Ant 1.10.x users should upgrade to 1.10.11 or later.
