NVD Description
Note: Versions mentioned in the description apply only to the upstream leptonlib package and not the leptonlib package as distributed by Ubuntu.
Leptonica 1.74.4 constructs unintended pathnames (containing duplicated path components) when operating on files in /tmp subdirectories, which might allow local users to bypass intended file restrictions by leveraging access to a directory located deeper within the /tmp directory tree, as demonstrated by /tmp/ANY/PATH/ANY/PATH/input.tif.
