RHEL 7 : rest (RHSA-2015:2237)

high Nessus Plugin ID 86977

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated rest packages that fix one security issue are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The rest library was designed to make it easier to access web services that claim to be RESTful. A RESTful service should have URLs that represent remote objects, which methods can then be called on.

It was found that the OAuth implementation in librest, a helper library for RESTful services, incorrectly truncated the pointer returned by the rest_proxy_call_get_url call. An attacker could use this flaw to crash an application using the librest library.
(CVE-2015-2675)

All users of rest are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, all applications using librest must be restarted for the update to take effect.

Solution

Update the affected rest, rest-debuginfo and / or rest-devel packages.
