RHEA-2012:0974 - rpcbind enhancement update


Synopsis

rpcbind enhancement update

Type/Severity

Product Enhancement Advisory (none)

Topic

Enhanced rpcbind packages that add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The rpcbind utility maps RPC (Remote Procedure Call) services to the ports on which the services listen and allows the host to make RPC calls to the RPC server.

This update adds the following enhancement:

  • The rpcbind tool did not drop supplementary groups and the groups remained available after rpcbind downgraded from root-group privileges. As a security hardening measure, rpcbind now drops root privileges correctly, running as a non-root user after it has bound to its privileged network port. (BZ#726954)

Users of rpcbind are advised to upgrade to these enhanced packages, which add this enhancement.

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
