Vixie cron is an implementation of the popular UNIX program that runs user-specified programs at periodic scheduled times.
|
|
|
|
When a parsing error occurs after a modification operation, crontab will fail to drop privileges correctly for subsequent modification operations.
|
|
|
|
This vulnerability may be exploited to gain root privileges locally.
