Description

A use-after-free security bug in rpcbind was fixed which could lead to a remote denial of service.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
