This bug report was also filed in Ubuntu and can be found at http://launchpad.net/bugs/607328 The description, from segooon, follows: Binary package hint: feh Hi, I've just discovered that feh is vulnerable to rewriting any user file: tmpname_timestamper = estrjoin("", "/tmp/feh_", cppid, "_", basename, NULL); .... execlp("wget", "wget", "-N", "-O", tmpname_timestamper, newurl, quiet, (char*) NULL); If attacker knows PID of feh and knows the URL, it can create the link to any user file. wget would overwrite it.
