Category: None Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: Yes Submitted By: https://www.google.com/accounts () >Assigned to: renzo davoli (rd235) Summary: unsafe use of dlopen(3) Initial Comment: Hello, while performing an audit of vde2 (https://bugs.launchpad.net/ubuntu/+source/vde2/+bug/776818) I found a bug; it may even be a security bug. If you decide this is a security issue, please contact the linux-distros security list to coordinate a release and request a CVE number. (See http://oss-security.openwall.org/wiki/mailing-lists/distros for details on using the linux-distros list. Note especially that [vs] is required in the Subject: header.) TRY_DLOPEN("%s%s", modname, MODULES_EXT); TRY_DLOPEN("%s%s/%s", homedir, USER_PLUGINS_DIR, modname); TRY_DLOPEN("%s%s/%s%s", homedir, USER_PLUGINS_DIR, modname, MODULES_EXT); TRY_DLOPEN("%s%s", PLUGINS_DIR, modname); TRY_DLOPEN("%s/%s%s", PLUGINS_DIR, modname, MODULES_EXT); It is generally considered poor form to load executable content from the current working directory (as this code does if getenv("HOME") fails), and loading code from a home directory seems suspect to me. However, I do not know the design well enough to make this determination myself. Please consider if this is unsafe or intentional. If it is intentional, make sure that the documentation accurately reflects the risk of allowing executable content to exist in current working directories or home directories. ---------------------------------------------------------------------- >Comment By: Daniele Lacamera (danielel) Date: 2013-03-07 12:28 Message: fixed in r555 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=611248&aid=3603899&group_id=95403 ------------------------------------------------------------------------------ Symantec Endpoint Protection 12 positioned as A LEADER in The Forrester Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the endpoint security space.
