RHBA-2013:0291 - Bug Fix Advisory

Topic

Updated rpcbind packages that fix two bugs and 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 fixes the following bugs:

• Previously, the rpcbind(8) man page referred to rpcbind(3) for which no entry

existed. This update adds the missing rpcbind(3) man page. (BZ#813898)

• Using Reverse Address Resolution Protocol (RARP) and the bootparams file for

booting Solaris or SPARC machines did not work properly. The SPARC systems sent
broadcast bootparams WHOAMI requests, but the answer was never sent back by
rpcbind. This bug has been fixed and rpcbind no longer discards the bootparams
WHOAMI requests in the described scenario. (BZ#864056)

This update also adds the following enhancement:

• When using the rpcbind's insecure mode via the "-i" option, non-root local

users are now allowed to set and unset calls from remote hosts. (BZ#731542)

All users of rpcbind are advised to upgrade to these updated packages, which fix
these bugs and 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

Fixes

• BZ - 731542 - rpcbind without -i restricts set/unset to root user on localhost, so pmap_set fails for non-root users unless -i is used
• BZ - 813898 - No rpcbind entry in section 3 of the man pages as mentioned in rpcbind man page
