Description Arvid Requate univentionstaff 2016-10-05 12:34:46 CEST
+++ This bug was initially created as a clone of Bug #39421 +++

This security issue is fixed in upstream Debian package version 2.0.1-7+squeeze2:

* Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0 allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data (CVE-2015-1283)
Comment 1 Arvid Requate univentionstaff 2016-10-05 12:37:23 CEST
Upstream Debian package version 2.1.0-1+deb7u4 fixes these additional issues:

* unanticipated internal calls to srand (CVE-2012-6702)
* use of too little entropy (CVE-2016-5300)
