Packages
Details
As written in the advisory (Markdown source, shown as plain text).
The (1) file upload component and (2) File Abstraction Layer (FAL) in TYPO3 6.0.x before 6.0.8 and 6.1.x before 6.1.3 do not properly check file extensions, which allow remote authenticated editors to execute arbitrary PHP code by uploading a .php file.
