Last modified: 2018-08-15 16:20:28 CEST
New Debian xerces-c 3.1.1-5.1+deb8u4 fixes: This update addresses the following issue(s): * CVE_2012-0880 is open * In Apache Xerces-C XML Parser library before 3.2.1, processing of external DTD paths can result in a null pointer dereference under certain conditions. (CVE-2017-12627) 3.1.1-5.1+deb8u4 (Thu, 26 Apr 2018 00:28:32 -0400) * 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. * CVE-2017-12627 xerces-c: Null pointer dereference while processing the path to DTD allows denial of service (CVE-2017-12627)
