| Fixed In Version: | glibc-2.28-189.5.el8_6 | Doc Type: | Bug Fix |
| Doc Text: |
Cause: The tempnam function in Red Hat Enterprise Linux 8.4 and later used time-derived randomness for choosing paths.
Consequence: When invoked repeatedly in quick succession, tempnam does not produce the full set of possible file names.
Fix: The new implementation uses getrandom to increase the randomness of generated file names.
Result: More distinct file names are generated by the tempnam function.
