11 July 2011
A security issue affects these releases of Ubuntu and its derivatives:

OProfile could be made to run programs as an administrator.

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)
