| Fixed In Version: | procinfo-18-19.el5_7.1 | Doc Type: | Bug Fix |
| Doc Text: |
Previously, the procinfo command calculated the system idle time in a way that caused arithmetic overflows. As a consequence, procinfo displayed the system idle time incorrectly, which eventually resulted in buffer overflows. With this update, procinfo has been modified to convert variables to a larger data type before they are used in the calculation so that procinfo now always displays the system idle time correctly. Buffer overflows no longer occur under these circumstances.
