sample.sh in maildirsync 1.1 allows local users to append data to arbitrary files via a symlink attack on a /tmp/maildirsync-*.#####.log temporary file.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
