Summary
The remote host is missing an update for the 'expat' package(s) announced via the DSA-1912-1 advisory.
Insight
Insight
It was discovered that there was a heap-based buffer overread vulnerability in expat, an XML parsing library. A specially-crafted XML input could fool the parser into changing from DTD parsing to document parsing too early, a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer overread.
Affected Software
Affected Software
'expat' package(s) on Debian Linux.
Detection Method

Solution
Solution
For Debian 8 'Jessie', this issue has been fixed in expat version 2.1.0-6+deb8u6. We recommend that you upgrade your expat packages.
