Upstream information
Description
There are multiple issues.1. Updates to the XAPI database sanitise input strings, but try
generating the notification using the unsanitised input. This
causes the database's event thread to terminate and cease further
processing.
2. XAPI's UTF-8 encoder implements v3.0 of the Unicode spec, but XAPI
uses libraries which conform to the stricter v3.1 of the Unicode
spec. This causes some strings to be accepted as valid UTF-8 by
XAPI, but rejected by other libraries in use. Notably, such strings
can be entered into the database, after which the database can no
longer be loaded.
3. There is no input sanitisation for Map/Set updates on objects in the
XAPI database.

Note from the SUSE Security Team on the xen package
This issue likely only affects the XEN hypervisor itself, unless otherwise stated. The userland utilities in -tools and libraries in -libs are shipped together with the xen hypervisor as they are built from one source and do not contain hypervisor specific fixes. SUSE Bugzilla entry: 1248809 [RESOLVED / INVALID] No SUSE Security Announcements cross referenced.Status of this issue by product and package
