This has been assigned CVE-2011-2713.

Comment 14 Huzaifa S. Sidhpurwala 2011-10-05 10:40:46 UTC 
It initially appeared that this flaw may be exploitable similar to CVE-2010-3452, where an OOB Read caused Arbitrary Code Execution. However in the case of this particular flaw, the junk data read is just parsed into an internal representation of properties and the maximum harm this should cause in application crash (Denial Of Service). 

Timeline:
- Reported to securityteam on 25-July-2011
- Recieved a reply (with tdf-security.org copied) on the same date 
- Release date changed with a few delays in between
- Release on 5-Oct-2011


Statement:

This issue results in an OOB read which is not exploitable for arbitrary code execution and can simply cause a crash. We do not consider this as a security issue.
