Package : xerces-c
Version : 3.1.1-3+deb7u5
CVE ID : CVE-2017-12627
Debian Bug : 894050

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.

For Debian 7 "Wheezy", these problems have been fixed in version
3.1.1-3+deb7u5.

We recommend that you upgrade your xerces-c packages.
