Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal versions before 7.4.3.16 are affected, including 7.2.0 through 7.4.3.15 and older unsupported versions. A remote authenticated user can manipulate a request parameter that controls the Image Uploader's file size limit, allowing very large files to be written to the system's temp folder, which can cause denial of service. Upgrade to Liferay Portal 7.4.3.16 or later.
