RHEL 6 : libtirpc (RHSA-2013:0884)

high Nessus Plugin ID 66707

Language:

Synopsis

The remote Red Hat host is missing a security update for libtirpc.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2013:0884 advisory.

These packages provide a transport-independent RPC (remote procedure call) implementation.

A flaw was found in the way libtirpc decoded RPC requests. A specially-crafted RPC request could cause libtirpc to attempt to free a buffer provided by an application using the library, even when the buffer was not dynamically allocated. This could cause an application using libtirpc, such as rpcbind, to crash. (CVE-2013-1950)

Red Hat would like to thank Michael Armstrong for reporting this issue.

Users of libtirpc should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libtirpc must be restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL libtirpc package based on the guidance in RHSA-2013:0884.
