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.
