DESCRIPTION:
Debian has issued an update for oprofile. This fixes a weakness,
which can be exploited by malicious, local users to perform certain
actions with escalated privileges.
The weakness is caused due an error within the "set_event()" function
in the opcontrol script, which does not properly sanitize the event
names before using then in an eval command and can be exploited to
execute arbitrary shell commands.
Successful exploitation requires that the opcontrol script is added
to /etc/sudoers.
SOLUTION:
Apply updated packages via the apt-get package manager.
PROVIDED AND/OR DISCOVERED BY:
Reported by Stephane Chauveau in a Debian bug.
