This bug report was also filed in Ubuntu and can be found at http://launchpad.net/bugs/607309 The description, from segooon, follows: Binary package hint: conky Hi, I've just discovered that conky is vulnerable to rewriting any user file: char *getSkillname(const char *file, int skillid) .... if (!file_exists(file)) { skilltree = getXmlFromAPI(NULL, NULL, NULL, EVEURL_SKILLTREE); writeSkilltree(skilltree, file); free(skilltree); } getXmlFromAPI() can be executed for a long time (e.g. bad connection), so between file_exists() and write_file() attacker can create link to any user file named "/tmp/.cesf". Attacker can choose the time when to create the link by watching for network connections.
