Hello Josh, Steve, vendors, It was found that oprofile profiling system did not properly sanitize the content of event argument, provided to oprofile profiling control utility (opcontrol). If a local unprivileged user was authorized by sudoers file to run the opcontrol utility, they could use the flaw to escalate their privileges (execute arbitrary code with the privileges of the privileged system user, root). Different vulnerability than CVE-2006-0576. References: [1] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=624212 [2] https://bugzilla.redhat.com/show_bug.cgi?id=700883 Could you allocate a CVE id for this? Thank you & Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team P.S.: Oprofile is not encouraged to be run under sudo, but still should not allow escalation of privileges.
