CVE-2021-36374 is a medium-severity flaw (CVSS 5.5) affecting ant, agile engineering data management, agile product lifecycle management. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
When reading a specially crafted ZIP archive, or a derived formats, an Apache Ant build can be made to allocate large amounts of memory that leads to an out of memory error, even for small inputs. This can be used to disrupt builds using Apache Ant. Commonly used derived formats from ZIP archives are for instance JAR files and many office files. Apache Ant prior to 1.9.16 and 1.10.11 were affected.
