Debian DLA-937-1 : rpcbind security update

High Nessus Plugin ID 100109

Synopsis

The remote Debian host is missing a security update.

Description

Guido Vranken discovered that incorrect memory management in libtirpc, a transport-independent RPC library used by rpcbind and other programs may result in denial of service via memory exhaustion (depending on memory management settings).

For Debian 7 'Wheezy', these problems have been fixed in version 0.2.0-8+deb7u2.

We recommend that you upgrade your rpcbind packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected rpcbind package.
