An essential patch for CentOS 8 focusing on critical vulnerabilities is now available. Discover the details and mitigation strategies.
Updated rest packages that fix one security issue are now available for Red Hat Enterprise Linux 7

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258

Summary

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.
