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.
