Updated certmonger packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The certmonger daemon monitors certificates which have been registered with it, and as a certificate's not-valid-after date approaches, the daemon can optionally attempt to obtain a fresh certificate from a supported CA.
The certmonger packages have been upgraded to upstream version 0.61, which provides a number of bug fixes and enhancements over the previous version. (BZ#827611)
- When certmonger was set up to not attempt to obtain a new certificate and the certificate's valid remaining time crossed a configured time to live (TTL) threshold, certmonger warned of a certificate's impending not-valid-after date. Certmonger then immediately logged the warning again, and continued to do so indefinitely, causing the /var/log/messages file to fill up with warnings. This bug has been fixed and certmonger returns a warning again only when another configured TTL threshold is crossed or the service is restarted.
- When certmonger attempts to save a certificate to an NSS database, it necessarily opens that database for writing. Previously, if any other process, including any other certmonger tasks that could require access to that database, had the database open for writing, that database could become corrupted. This update backports changes from later versions of certmonger which change its behavior. Now, actions that could result in database modifications are only performed one at a time.
All users of certmonger are advised to upgrade to these updated packages which fix these bugs and add these enhancements.
