Please Install the Updated Packages.
A vulnerability has been discovered and corrected in ipmitool: ipmievd as used in the ipmitool package uses 0666 permissions for its ipmievd.pid PID file, which allows local users to kill arbitrary processes by writing to this file (CVE-2011-4339). In Mandriva the ipmievd daemon from the ipmitool package does not have an initscript to start and stop the service, however one could rather easily craft an initscript or start the service by other means rendering the system vulnerable to this issue. The updated packages have been patched to correct this issue.
ipmitool on Mandriva Linux 2010.1, Mandriva Linux 2010.1/X86_64, Mandriva Enterprise Server 5, Mandriva Enterprise Server 5/X86_64
