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.
