Descriptions

An issue has been discovered in GitLab CE/EE affecting all versions starting from 11.9. GitLab was not properly validating image files that were passed to a file parser which resulted in a remote command execution.

Se ha detectado un problema en GitLab CE/EE que afecta a todas las versiones a partir de 11.9. GitLab no estaba comprobado apropiadamente archivos de imagen que fueron pasados a un analizador de archivos, lo que resultó en una ejecución de comando remoto

GitHub Community and Enterprise Editions that utilize the ability to upload images through GitLab Workhorse are vulnerable to remote code execution. Workhorse passes image file extensions through ExifTool, which improperly validates the image files.
