USN-1166-1: OProfile vulnerabilities

11 July 2011

OProfile could be made to run programs as an administrator.



  • oprofile - System-wide profiler for Linux systems


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)
