Debian Security Advisory 2254-2

Debian Security Advisory 2254-2
Posted Jul 16, 2011
Authored by Debian | Site debian.org

Debian Linux Security Advisory 2254-2 - Jamie Strandboge noticed that the patch proposed to fix CVE-2011-1760 in OProfile has been incomplete. OProfile is a performance profiling tool which is configurable by opcontrol, its control utility. Stephane Chauveau reported several ways to inject arbitrary commands in the arguments of this utility. If a local unprivileged user is authorized by sudoers file to run opcontrol as root, this user could use the flaw to escalate his privileges.
