feh contains a flaw that may allow a malicious local user to overwrite arbitrary files on the system. The issue is due to the 'feh_unique_filename()' function in 'src/utls.c' creating temporary files insecurely, specifically by generating predictable filenames. It is possible for a local attacker to use a symlink attack to cause the program to unexpectedly write to, or overwrite an attacker specified file.
