Synopsis
Moderate: rpcbind security update
Type/Severity
Security Advisory: Moderate
Topic
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.
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.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
