3. Description:

The rpcbind utility is a server that converts RPC program numbers into universal addresses. It must be running on the host to be able to make RPC calls on a server on that machine.

A use-after-free flaw related to the PMAP_CALLIT operation and TCP/UDP connections was discovered in rpcbind. A remote attacker could possibly exploit this flaw to crash the rpcbind service by performing a series of UDP and TCP calls. (CVE-2015-7236)

All rpcbind users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. If the rpcbind service is running, it will be automatically restarted after installing this update.

4. Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.
