| Doc Text: |
The missing exit(1) function call in the underlying code of the sepolgen-ifgen utility could cause the restorecond daemon to access already freed memory when retrieving user's information. This would cause restorecond to terminate unexpectedly with a segmentation fault. With this update, restorecond has been modified to check the return value of the getpwuid() function to avoid this situation.
