CVE-2021-36373: Apache Ant TAR archive denial of service vulnerability

Published Jul 13, 2021
·
Updated

Apache Ant is vulnerable to a denial of service, caused by an out-of-memory error when large amounts of memory are allocated. By persuading a victim to open a specially-crafted TAR archive, a remote attacker could exploit this vulnerability to cause the application to crash.

Other sources

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.
