oprofile vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

OProfile could be made to run programs as an administrator.

Software Description:
- oprofile: System-wide profiler for Linux systems

Details:

Stephane Chauveau discovered that OProfile did not properly perform input
validation when processing arguments to opcontrol. A local user who is
allowed to run opcontrol with privileges could exploit this to run
arbitrary commands as the privileged user. (CVE-2011-1760, CVE-2011-2471)

Stephane Chauveau discovered a directory traversal vulnerability in
OProfile when processing the --save argument to opcontrol. A local user
could exploit this to overwrite arbitrary files with the privileges of
the user invoking the program. (CVE-2011-2472)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
  oprofile                        0.9.6-1ubuntu4.4

In general, a standard system update will make all the necessary changes.
