Ant is a Java-based build tool similar to ‘make’ that uses XML configuration files.
Apache Ant was found to be using multiple insecure temporary files which may disclose sensitive information or execute code from an unsafe local location.
A local attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
There is no known workaround at this time.
All Apache Ant users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/ant-1.10.8"
