3. Description:
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.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
