I would like to update xerces-c in a future point release. This update
will fix one issue:
* Fix CVE-2017-12627: Alberto Garcia, Francisco Oca and Suleman Ali of
Offensive Research discovered that the Xerces-C XML parser mishandles
certain kinds of external DTD references, resulting in dereference of a
NULL pointer while processing the path to the DTD. The bug allows for a
denial of service attack in applications that allow DTD processing and do
not prevent external DTD usage, and could conceivably result in remote code
execution.
The CVE was deemed by the security team to not be critical enough for a
DSA, but they suggested that it might be included in a point release.
This issue has been fixed in unstable, and I have attached a debdiff
that reflects the desired changes.
Regards,
Bill
