===================================================================== Red Hat Security Advisory
Synopsis: Moderate: rpcbind security update Advisory ID: RHSA-2016:0005-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0005.html Issue date: 2016-01-07 CVE Names: CVE-2015-7236 =====================================================================
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64
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.
