CVE-2017-18196
Last modified
CVE-2017-18196 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
