The issue is that the LD_POINTER_GUARD in the environment is not sanitized allowing local attackers easily to bypass the pointer guarding protection on set-user-ID and set-group-ID programs. Details and PoC at: http://hmarco.org/bugs/glibc_ptr_mangle_weakness.html A patch is already sent to Glibc maintainers. This issue is similar to http://hmarco.org/bugs/CVE-2013-4788.html but now affect to dynamic linked applications. Could you please assign a CVE ? -- Hector Marco-Gisbert @ http://hmarco.org/ Cyber Security Researcher @ http://cybersecurity.upv.es Universitat Politècnica de València (Spain)
