Description


Updated rpcbind packages that fix one security issue are now available for
Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

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.
